28 And it shall be Aaron's and his sons' by a statute for ever, from the children of Israel: for it [is] a heave-offering: and it shall be a heave-offering from the children of Israel of the sacrifice of their peace-offerings, [even] their heave-offering to the LORD.
28
This is always to be the perpetual share from the Israelites for Aaron and his sons. It is the contribution the Israelites are to make to the LORD from their fellowship offerings.
