From the first of your dough (ground grain) you shall give to the Lord an offering throughout your generations.

All the offerings of the holy things, which the Israelites offer to the Lord I have given to you and to your sons and your daughters with you as a continual allotment. It is an everlasting covenant of salt [that cannot be dissolved or violated] before the Lord to you and to your descendants with you.”

Likewise you shall also present an offering to the Lord from all your tithes, which you receive from the Israelites; and from it you shall give the Lord’s offering to Aaron the priest.

Out of all your gifts, you shall present every offering due to the Lord, from all the best of it, even the sacred part from them.’

Therefore you shall say to them, ‘When you have offered the best from it, then the rest shall be credited to the Levites as the product of the threshing floor, and as the product of the wine vat.

You will bear no sin because of it when you have offered the best of it; but you shall not profane the sacred gifts of the children of Israel, or you will die [because of it].’”
