Numbers 18:19

All the wave offerings of the holy things which the children of Israel offer to Yahweh, I have given you and your sons and your daughters with you, as a portion forever. It is a covenant of salt forever before Yahweh to you and to your offspring with you.”

All the heave offerings of the holy things, which the children of Israel offer unto the LORD, have I given thee, and thy sons and thy daughters with thee, by a statute for ever: it is a covenant of salt for ever before the LORD unto thee and to thy seed with thee.
