'Priests' in the Bible

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

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

Of them also will I take for priests [and] for Levites," says Yahweh.
