'Priests' in the Bible

And he sent Eliakim, who was over the household, and Shebna the scribe, and the elders of the priests, covered with sackcloth, unto Isaiah the prophet the son of Amoz.

But ye shall be named the priests of Jehovah; men shall call you the ministers of our God: ye shall eat the wealth of the nations, and in their glory shall ye boast yourselves.

And of them also will I take for priests and for Levites, saith Jehovah.
