1 If there be a controversy between men, and they come unto judgment, that the judges may judge them; then they shall justify the righteous, and condemn the wicked. 2 And it shall be, if the wicked man be worthy to be beaten, that the judge shall cause him to lie down, and to be beaten before his face, according to his fault, by a certain number. 3 Forty stripes he may give him, and not exceed: lest, if he should exceed, and beat him above these with many stripes, then thy brother should seem vile unto thee. 4 Thou shalt not muzzle the ox when he treadeth out the corn. 5 If brethren dwell together, and one of them die, and have no child, the wife of the dead shall not marry without unto a stranger: her husband's brother shall go in unto her, and take her to him to wife, and perform the duty of an husband's brother unto her. 6 And it shall be, that the firstborn which she beareth shall succeed in the name of his brother which is dead, that his name be not put out of Israel. 7 And if the man like not to take his brother's wife, then let his brother's wife go up to the gate unto the elders, and say, My husband's brother refuseth to raise up unto his brother a name in Israel, he will not perform the duty of my husband's brother. 8 Then the elders of his city shall call him, and speak unto him: and if he stand to it, and say, I like not to take her; 9 Then shall his brother's wife come unto him in the presence of the elders, and loose his shoe from off his foot, and spit in his face, and shall answer and say, So shall it be done unto that man that will not build up his brother's house. 10 And his name shall be called in Israel, The house of him that hath his shoe loosed. 11 When men strive together one with another, and the wife of the one draweth near for to deliver her husband out of the hand of him that smiteth him, and putteth forth her hand, and taketh him by the secrets: 12 Then thou shalt cut off her hand, thine eye shall not pity her. 13 Thou shalt not have in thy bag divers weights, a great and a small. 14 Thou shalt not have in thine house divers measures, a great and a small. 15 But thou shalt have a perfect and just weight, a perfect and just measure shalt thou have: that thy days may be lengthened in the land which the LORD thy God giveth thee. 16 For all that do such things, and all that do unrighteously, are an abomination unto the LORD thy God. 17 Remember what Amalek did unto thee by the way, when ye were come forth out of Egypt; 18 How he met thee by the way, and smote the hindmost of thee, even all that were feeble behind thee, when thou wast faint and weary; and he feared not God. 19 Therefore it shall be, when the LORD thy God hath given thee rest from all thine enemies round about, in the land which the LORD thy God giveth thee for an inheritance to possess it, that thou shalt blot out the remembrance of Amalek from under heaven; thou shalt not forget it.
[AD 55] 1 Corinthians on Deuteronomy 25:4
Am I not an apostle? am I not free? have I not seen Jesus Christ our Lord? are not ye my work in the Lord? If I be not an apostle unto others, yet doubtless I am to you: for the seal of mine apostleship are ye in the Lord. Mine answer to them that do examine me is this, Have we not power to eat and to drink? Have we not power to lead about a sister, a wife, as well as other apostles, and as the brethren of the Lord, and Cephas? Or I only and Barnabas, have not we power to forbear working? Who goeth a warfare any time at his own charges? who planteth a vineyard, and eateth not of the fruit thereof? or who feedeth a flock, and eateth not of the milk of the flock? Say I these things as a man? or saith not the law the same also? For it is written in the law of Moses, Thou shalt not muzzle the mouth of the ox that treadeth out the corn. [Deuteronomy 25:4] Doth God take care for oxen? Or saith he it altogether for our sakes? For our sakes, no doubt, this is written: that he that ploweth should plow in hope; and that he that thresheth in hope should be partaker of his hope. If we have sown unto you spiritual things, is it a great thing if we shall reap your carnal things? If others be partakers of this power over you, are not we rather? Nevertheless we have not used this power; but suffer all things, lest we should hinder the gospel of Christ.
[AD 64] 1 Timothy on Deuteronomy 25:4
Let the elders that rule well be counted worthy of double honour, especially they who labour in the word and doctrine. For the scripture saith, Thou shalt not muzzle the ox that treadeth out the corn. And, The labourer is worthy of his reward. [Deuteronomy 25:4]
[AD 380] Apostolic Constitutions on Deuteronomy 25:4
Let him use those tenths and first-fruits, which are given according to the command of God, as a man of God; as also let him dispense in a right manner the free-will offerings which are brought in on account of the poor, to the orphans, the widows, the afflicted, and strangers in distress, as having that God for the examiner of his accounts who has committed the disposition to him. Distribute to all those in want with righteousness, and yourselves use the things which belong to the Lord, but do not abuse them; eating of them, but not eating them all up by yourselves: communicate with those that are in want, and thereby show yourselves unblameable before God. For if you shall consume them by yourselves, you will be reproached by God, who says to such unsatiable people, who alone devour all, "You eat up the milk, and clothe yourselves with the wool;" [Ezekiel 34:3] and in another passage, "Must you alone live upon the earth"? [Isaiah 5:8] Upon which account you are commanded in the law, "You shall love your neighbour as yourself." [Leviticus 19:18] Now we say these things, not as if you might not partake of the fruits of your labours; for it is written, "You shall not muzzle the mouth of the ox which treads out the grain;" [Deuteronomy 25:4; 1 Corinthians 9:9] but that you should do it with moderation and righteousness. As, therefore, the ox that labours in the threshing-floor without a muzzle eats indeed, but does not eat all up; so do you who labour in the threshing-floor, that is, in the Church of God, eat of the Church: which was also the case of the Levites, who served in the tabernacle of the testimony, which was in all things a type of the Church.

[AD 1781] Richard Challoner on Deuteronomy 25:4
Not muzzle: St. Paul understands this of the spiritual labourer in the church of God, who is not to be denied his maintenance. 1 Cor. 9. 8, 9, 10.
[AD 60] Matthew on Deuteronomy 25:5
The same day came to him the Sadducees, which say that there is no resurrection, and asked him, Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother. [Deuteronomy 25:5] Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother: Likewise the second also, and the third, unto the seventh. And last of all the woman died also. Therefore in the resurrection whose wife shall she be of the seven? for they all had her. Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God. For in the resurrection they neither marry, nor are given in marriage, but are as the angels of God in heaven. But as touching the resurrection of the dead, have ye not read that which was spoken unto you by God, saying, I am the God of Abraham, and the God of Isaac, and the God of Jacob? God is not the God of the dead, but of the living. And when the multitude heard this, they were astonished at his doctrine.
[AD 430] Augustine of Hippo on Deuteronomy 25:5
In the third book, then, when I was solving the question of how it was possible for Joseph to have two fathers, I indeed said that “he was begotten by one and adopted by the other.” But I should have mentioned too the kind of adoption, for what I said sounds as if another living father had adopted him. The law, however, also adopted the children of the deceased by ordering that “a brother marry the wife” of his childless, deceased brother and “raise up seed” by the same woman “for his deceased brother.” In this way the explanation of this matter of the two fathers of one man is indeed made clearer.

[AD 430] Augustine of Hippo on Deuteronomy 25:9
The role of holy women was different in the times of the prophets. Obedience, not concupiscence, impelled women to marry for the propagation of the people of God, among whom the forerunners of Christ were sent in advance. For this people, by the things that happened to them as a type, whether they recognized these types or not, were indeed prophetic of Christ, from whom Christ was to take flesh. Hence, in order that this race might be multiplied, the man who did not raise up seed in Israel was held accursed by sentence of the law. That is why holy women were animated by the pious desire of offspring rather than by desire. We may rightly believe that they would not have sought the marriage union if children could have been obtained in any other way.

[AD 1781] Richard Challoner on Deuteronomy 25:17
Amalec: This order for destroying the Amalecites, in the mystical sense, showeth how hateful they are to God, and what punishments they are to look for from his justice, who attack and discourage his servants when they are but just come out, as it were, of the Egypt of this wicked world and being yet weak and fainthearted, are but beginning their journey to the land of promise.
