Deuteronomy 12:7, 18

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.

but thou must eat them before the LORD thy God in the place which the LORD thy God shall choose, thou, and thy son, and thy daughter, and thy manservant, and thy maidservant, and the Levite that is within thy gates: and thou shalt rejoice before the LORD thy God in all that thou puttest thine hands unto.
