'Trier' in the Bible

Let, I pray Thee be ended the evil of the wicked, And establish Thou the righteous, And a trier of hearts and reins is the righteous God.

A refining pot is for silver, and a furnace for gold, And the trier of hearts is Jehovah.

And, O Jehovah of Hosts, trier of the righteous, Beholder of reins and heart, I do see Thy vengeance out of them, For unto Thee I have revealed my cause.

Because it is a trier, And what if even the sceptre it is despising? It shall not be, an affirmation of the Lord Jehovah.
