Deuteronomy 16:10 Meaning and Commentary

Deuteronomy 16:10

And thou shall keep the feast of weeks unto the Lord thy God,
&c.] The feast of Pentecost, at which time the Spirit was poured down upon the apostles, ( Acts 2:1 )

with a tribute of a freewill offering of thine hand;
there were two wave loaves which were ordered to be brought and seven lambs, one young bullock and two rams for a burnt offering, together with the meat and drink offerings belonging thereunto, and a kid of the goats for a sin offering, and two lambs for a peace offering, ( Leviticus 23:17-19 ) , and besides all this, there was to be a voluntary contribution brought in their hands; for this was one of those feasts at which all the males were to appear before the Lord, and none of them empty:

which thou shalt give
unto the Lord thy God,

according as the Lord thy God hath blessed thee;
no certain rate was fixed, it was to be a free gift, and in proportion to a man's abilities, or what the Lord had blessed him with.
