וְקִדַּשְׁתּ֔וֹ כִּֽי־אֶת־לֶ֥חֶם אֱלֹהֶ֖יךָ ה֣וּא מַקְרִ֑יב קָדֹשׁ֙ יִֽהְיֶה־לָּ֔ךְ כִּ֣י קָד֔וֹשׁ אֲנִ֥י יְהוָ֖ה מְקַדִּשְׁכֶֽם׃
Thou shalt sanctify him therefore; for he offereth the bread of thy God; he shall be holy unto thee; for I the LORD, who sanctify you, am holy.
Shenei Luchot HaBerit
Commandment 269 instructs the Jewish people to accord honour to the priests; the Torah says: וקדשתו כי את לחם אלוקיך הוא מקריב, "You shall sanctify him, for he offers the bread of your G–d" (21,8).
