1 Observe the month of Abib, and keep the passover unto the LORD thy God: for in the month of Abib the LORD thy God brought thee forth out of Egypt by night. 2 Thou shalt therefore sacrifice the passover unto the LORD thy God, of the flock and the herd, in the place which the LORD shall choose to place his name there. 3 Thou shalt eat no leavened bread with it; seven days shalt thou eat unleavened bread therewith, even the bread of affliction; for thou camest forth out of the land of Egypt in haste: that thou mayest remember the day when thou camest forth out of the land of Egypt all the days of thy life. 4 And there shall be no leavened bread seen with thee in all thy coast seven days; neither shall there anything of the flesh, which thou sacrificedst the first day at even, remain all night until the morning. 5 Thou mayest not sacrifice the passover within any of thy gates, which the LORD thy God giveth thee: 6 But at the place which the LORD thy God shall choose to place his name in, there thou shalt sacrifice the passover at even, at the going down of the sun, at the season that thou camest forth out of Egypt. 7 And thou shalt roast and eat it in the place which the LORD thy God shall choose: and thou shalt turn in the morning, and go unto thy tents. 8 Six days thou shalt eat unleavened bread: and on the seventh day shall be a solemn assembly to the LORD thy God: thou shalt do no work therein. 9 Seven weeks shalt thou number unto thee: begin to number the seven weeks from such time as thou beginnest to put the sickle to the corn. 10 And thou shalt keep the feast of weeks unto the LORD thy God with a tribute of a freewill offering of thine hand, which thou shalt give unto the LORD thy God, according as the LORD thy God hath blessed thee: 11 And thou shalt rejoice before the LORD thy God, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite that is within thy gates, and the stranger, and the fatherless, and the widow, that are among you, in the place which the LORD thy God hath chosen to place his name there. 12 And thou shalt remember that thou wast a bondman in Egypt: and thou shalt observe and do these statutes. 13 Thou shalt observe the feast of tabernacles seven days, after that thou hast gathered in thy corn and thy wine: 14 And thou shalt rejoice in thy feast, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite, the stranger, and the fatherless, and the widow, that are within thy gates. 15 Seven days shalt thou keep a solemn feast unto the LORD thy God in the place which the LORD shall choose: because the LORD thy God shall bless thee in all thine increase, and in all the works of thine hands, therefore thou shalt surely rejoice. 16 Three times in a year shall all thy males appear before the LORD thy God in the place which he shall choose; in the feast of unleavened bread, and in the feast of weeks, and in the feast of tabernacles: and they shall not appear before the LORD empty: 17 Every man shall give as he is able, according to the blessing of the LORD thy God which he hath given thee. 18 Judges and officers shalt thou make thee in all thy gates, which the LORD thy God giveth thee, throughout thy tribes: and they shall judge the people with just judgment. 19 Thou shalt not wrest judgment; thou shalt not respect persons, neither take a gift: for a gift doth blind the eyes of the wise, and pervert the words of the righteous. 20 That which is altogether just shalt thou follow, that thou mayest live, and inherit the land which the LORD thy God giveth thee. 21 Thou shalt not plant thee a grove of any trees near unto the altar of the LORD thy God, which thou shalt make thee. 22 Neither shalt thou set thee up any image; which the LORD thy God hateth.
[AD 435] John Cassian on Deuteronomy 16:9
There was plainly realized the number of this festival, which we read was figuratively foreshadowed in the Old Testament too, when it was ordered that at the end of seven weeks the bread of first fruits was to be offered to the Lord by the priests. This in very truth is recognized as having been offered to the Lord by the preaching of the apostles with which they are said to have exhorted the people on that day. This was the true bread of the first fruits, which was proffered at the beginning of the new teaching, when five thousand men were filled with the gift of its food and which consecrated to the Lord a Christian people newly born from the Jews.

[AD 253] Origen of Alexandria on Deuteronomy 16:10
An offering of “first fruits,” that is, from the beginning of the harvest, is commanded. If you remember well, the law commands this is to be done on the day of Pentecost. This was obviously given to them as a “shadow,” but the truth was reserved for us. For on the day of Pentecost, after they offered up the sacrifice of prayers, the church of the apostles received the first fruits of the coming of the Holy Spirit.

[AD 606] Paterius on Deuteronomy 16:16
He appears emptyhanded in the sight of the Lord who brings none of the fruits of his labor with him. One man seethes with desire to increase his power; another pants with longing to gather praise. But because the dying man leaves all these things behind, he appears before the Lord emptyhanded, for he brings nothing with him when he appears before the judge. Thus the law admonishes us to good effect when it says, “You will not appear emptyhanded in the sight of the Lord.” For the man who does not plan for the reward of a meritorious life by acting well appears emptyhanded in the sight of the Lord. The psalmist says of the just, “coming they will come rejoicing, carrying their sheaves.” They who come to the judge’s court carrying sheaves are the ones who display in themselves good works by which they merit life.

[AD 542] Caesarius of Arles on Deuteronomy 16:19
Those who hear cases should decide them justly and not accept bribes at the expense of the innocent, “for gifts blind the hearts of the wise and change the words of the just.” Otherwise, while they are acquiring money, they may lose their soul. No one obtains unjust profit without a just loss. Where the gain is, there is the loss: a gain in the money coffer but a loss in the conscience.

[AD 420] Jerome on Deuteronomy 16:20
In another place: “You shall follow justly after that which is just,” lest we turn from justice, by asserting our own view of truth, recalling the experience of Saul and Agag.
