Leviticus 22:15

Leviticus 22:15

And they shall not profane the holy things of the children of
Israel, which they offer unto the Lord.
] By causing or suffering strangers to eat of them; so Jarchi, referring the words to the priests, who should be careful that strangers ate not of sacred things; or by the strangers themselves eating them, whereby they were profaned and used as common things.
