Numbers 18:26 Thus speak unto the Levites, and say unto them, When ye take of the children of Israel the tithes which I have given you from them for your inheritance,
then ye shall offer up an heave offering of it for the LORD, [
even]
a tenth [part] of the tithe.
Exodus 29:28 And it shall be
Aaron's and his sons' by a statute for ever from the children of Israel: for it
[is] an heave offering: and it shall be an heave offering from the children of Israel of the
sacrifice of their peace offerings, [
even] their heave offering unto the LORD.
