'Priestly' in the Bible

And it shall come to pass that every one that is left of thy house shall come to crouch to him for a small piece of silver and for a cake of bread, and shall say, Put me, I pray thee, into one of the priestly offices, that I may eat a morsel of bread.

I will greatly rejoice in Jehovah, my soul shall be joyful in my God; for he hath clothed me with the garments of salvation, he hath covered me with the robe of righteousness, as a bridegroom decketh himself with the priestly turban, and as a bride adorneth herself with her jewels.
