And of it he shall offer one out of the whole oblation
[for] an heave offering unto the Lord
That is, one out of the unleavened cakes, and out of the unleavened wafers, and out of the cakes fried, and out of the cakes leavened; lo, says Aben Ezra, four at least, and the truth is, adds he, there were ten; and so Maimonides F8 says, the priest took out of all the four cakes, one out of every sort, as it is said, "and of it he shall offer one"
and it shall be the priest's that sprinkleth the blood of the peace
that is, that part of the cakes and bread, which is offered as an heave offering to the Lord, was the portion of the priests; and so Maimonides F9 says,
``the bread waved (rather heaved) with the thank offering was eaten by the priests, and the rest of the bread by the owners.''
