eat before

5
But unto the place which the LORD your God shall choose out of all your tribes to put his name there, even unto his habitation shall ye seek, and thither thou shalt come:
6
And thither ye shall bring your burnt offerings, and your sacrifices, and your tithes, and heave offerings of your hand, and your vows, and your freewill offerings, and the firstlings of your herds and of your flocks:
7
And there ye shall eat before the LORD your God, and ye shall rejoice in all that ye put your hand unto, ye and your households, wherein the LORD thy God hath blessed thee.
