Thou shalt eat it - in the place which the Lord shall choose - Thus God in his mercy made their duty and interest go hand in hand. And in every case God acts thus with his creatures; well, therefore, might Satan ask, Doth Job serve God for naught? No! nor does God design that any man should.
Thou shalt eat it before the Lord thy God, year by year,.... Which, if understood of male firstlings, as in connection with the preceding verse, only priests might eat of them, being devoted to the Lord; so Jarchi says, to the priest he speaks; but if this respects the Israelites in common, then they must be understood either of female firstlings or second firstlings, which the people voluntarily separated, and which they were not to eat in their own houses:
but in the place which the Lord shall choose, which was the city of Jerusalem; see Deuteronomy 12:5,

Year by year - Namely, in the solemn feasts which returned upon them every year.
