1 Samuel 2:35
King James Version (KJV)
“And I will raise me up a faithful priest, that shall do according to that which is in mine heart and in my mind: and I will build him a sure house; and he shall walk before mine anointed for ever.”

YHWH, the Word of Elohim, will purify the humbled, says Isaiah (close to 300 years later), who will be called priests, ministers of our Elohim:

Isaiah 61:6
And you will be called priests of the Lord (YHWH-the Word of Elohim), you will be named ministers of our God (Elohim). You will feed on the wealth of nations, and in their riches you will boast.

HalleluYH, Amein, Amein.
