Leviticus 24:7-10

⁷And thou shalt put upon them the dearest frankincense, that the bread may be for a memorial of the oblation of the Lord.

⁸Every sabbath they shall be changed before the Lord, being received of the children of Israel by an everlasting covenant:

⁹And they shall be Aaron’s and his sons’, that they may eat them in the holy place: because it is most holy of the sacrifices of the Lord by a perpetual right.

¹⁰And behold there went out the son of a woman of Israel, whom she had of an Egyptian, among the children of Israel, and fell at words in the camp with a man of Israel.
