:
1 Thou shalt not sacrifice unto the LORD thy God any bullock, or sheep, wherein is blemish, or any evilfavouredness: for that is an abomination unto the LORD thy God. 2 If there be found among you, within any of thy gates which the LORD thy God giveth thee, man or woman, that hath wrought wickedness in the sight of the LORD thy God, in transgressing his covenant, 3 And hath gone and served other gods, and worshipped them, either the sun, or moon, or any of the host of heaven, which I have not commanded; 4 And it be told thee, and thou hast heard of it, and inquired diligently, and, behold, it be true, and the thing certain, that such abomination is wrought in Israel: 5 Then shalt thou bring forth that man or that woman, which have committed that wicked thing, unto thy gates, even that man or that woman, and shalt stone them with stones, till they die. 6 At the mouth of two witnesses, or three witnesses, shall he that is worthy of death be put to death; but at the mouth of one witness he shall not be put to death. 7 The hands of the witnesses shall be first upon him to put him to death, and afterward the hands of all the people. So thou shalt put the evil away from among you. 8 If there arise a matter too hard for thee in judgment, between blood and blood, between plea and plea, and between stroke and stroke, being matters of controversy within thy gates: then shalt thou arise, and get thee up into the place which the LORD thy God shall choose; 9 And thou shalt come unto the priests the Levites, and unto the judge that shall be in those days, and inquire; and they shall shew thee the sentence of judgment: 10 And thou shalt do according to the sentence, which they of that place which the LORD shall choose shall shew thee; and thou shalt observe to do according to all that they inform thee: 11 According to the sentence of the law which they shall teach thee, and according to the judgment which they shall tell thee, thou shalt do: thou shalt not decline from the sentence which they shall shew thee, to the right hand, nor to the left. 12 And the man that will do presumptuously, and will not hearken unto the priest that standeth to minister there before the LORD thy God, or unto the judge, even that man shall die: and thou shalt put away the evil from Israel. 13 And all the people shall hear, and fear, and do no more presumptuously. 14 When thou art come unto the land which the LORD thy God giveth thee, and shalt possess it, and shalt dwell therein, and shalt say, I will set a king over me, like as all the nations that are about me; 15 Thou shalt in any wise set him king over thee, whom the LORD thy God shall choose: one from among thy brethren shalt thou set king over thee: thou mayest not set a stranger over thee, which is not thy brother. 16 But he shall not multiply horses to himself, nor cause the people to return to Egypt, to the end that he should multiply horses: forasmuch as the LORD hath said unto you, Ye shall henceforth return no more that way. 17 Neither shall he multiply wives to himself, that his heart turn not away: neither shall he greatly multiply to himself silver and gold. 18 And it shall be, when he sitteth upon the throne of his kingdom, that he shall write him a copy of this law in a book out of that which is before the priests the Levites: 19 And it shall be with him, and he shall read therein all the days of his life: that he may learn to fear the LORD his God, to keep all the words of this law and these statutes, to do them: 20 That his heart be not lifted up above his brethren, and that he turn not aside from the commandment, to the right hand, or to the left: to the end that he may prolong his days in his kingdom, he, and his children, in the midst of Israel.

The host of heaven: That is, the stars.
[AD 220] Tertullian on Deuteronomy 17:6
“Two angels, however, appeared there.” For just so many honorary companions were required by the Word of God, which usually prescribes “two witnesses.” Moreover, the women, returning from the sepulcher and from this vision of the angels were foreseen by Isaiah, when he says, “Come, you women, who return from the vision”;2 that is, “come” to report the resurrection of the Lord.

[AD 55] 1 Corinthians on Deuteronomy 17:7
I wrote unto you in an epistle not to company with fornicators: Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. But now I have written unto you not to keep company, if any man that is called a brother be a fornicator, or covetous, or an idolater, or a railer, or a drunkard, or an extortioner; with such an one no not to eat. For what have I to do to judge them also that are without? do not ye judge them that are within? But them that are without God judgeth. Therefore put away from among yourselves that wicked person. [Deuteronomy 17:7]
[AD 1781] Richard Challoner on Deuteronomy 17:8
[8] If thou perceive: Here we see what authority God was pleased to give to the church guides of the Old Testament, in deciding, without appeal, all controversies relating to the law; promising that they should not err therein; and surely he has not done less for the church guides of the New Testament.
[AD 430] Augustine of Hippo on Deuteronomy 17:11
Just as a person has to pick his way between fire and water so as to be neither burned nor drowned, so we should steer our way between the pinnacle of pride and the whirlpool of sloth, as it is written, “turning neither to the right nor to the left.” For there are some who, through fear of being carried up to the heights on the right, slip and are drowned on the left. Others … fear to be sucked in by the soft ease of sloth on the left and are ruined and destroyed by the ostentation of boasting on the other side, and [they] vanish into smoke and ashes.

[AD 379] Basil of Caesarea on Deuteronomy 17:20
You are a wayfarer, like to him who prayed, “Direct my steps.” “Give heed to yourself” that you may swerve not from the path, that you decline neither to the right nor the left. Keep to the king’s highway. The architect should lay the firm foundation of faith which is Jesus Christ and let the builder look to his materials: not wood, nor hay nor stubble but gold, silver, precious stones.
