Deuteronomy 12:26

“You are not allowed to eat within your gates the tithe of your grain or new wine or oil, or the firstborn of your herd or flock, or any of your votive offerings which you vow, or your freewill offerings, or the contribution of your hand.

rather it shall be a witness between us and you and between our generations after us, that we are to perform the service of Yahweh before Him with our burnt offerings and with our sacrifices and with our peace offerings, so that your sons will not say to our sons in time to come, “You have no portion in Yahweh.”’
