Deuteronomy 16:9-12

Of Pentecost

v. 9. Seven weeks shalt thou number unto thee, namely, from the sixteenth of Abib, or Nisan. Leviticus 23:15; begin to number the seven weeks from such time as thou beginnest to put the sickle to the corn, which was done on the sixteenth of Nisan, when the first-fruits of barley were offered to the Lord.

v. 10. And thou shalt keep the Feast of Weeks, or Pentecost, unto the Lord, thy God, with a tribute, or measure, of a free-will offering of thine hand, which thou shalt give unto the lord, thy god, according as the Lord, thy God, hath blessed thee, the offering thus being as rich as the worshiper desired, in proportion to the blessing which he had received at the Lord's hand. Exodus 23:15; Exodus 34:20;

v. 11. and thou shalt rejoice before the lord, thy god, Deuteronomy 12:7 to Deuteronomy 12:18, thou, and thy son, and thy daughter, and thy man-servant, 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. though only a one-day festival, Pentecost was celebrated with great joy, and the needs of the poor and forsaken were particularly stressed.

v. 12. and thou shalt remember that thou wast a bondman in Egypt; and thou shalt observe and do these statutes, always spurred on in these efforts by the remembrance of the wonderful redemption from the serfdom of Egypt. note that only that side of the festival is here touched upon which concerned the Israelite personally, the public sacrifices being described Numbers 28, 29.
