'Try' in the Bible

“I [the Lord] have set you as an assayer [O Jeremiah] and as a tester [of the ore] of My people,That you may know and analyze their acts.”

But You, O Lord, know me [and understand my devotion to You];You see me;And You examine the attitude of my heart toward You.Drag out the faithless like sheep for the slaughter [O Lord]And set them apart for the day of slaughter.

“I, the Lord, search and examine the mind,I test the heart,To give to each man according to his ways,According to the results of his deeds.

But, O Lord of hosts, You who examine the righteous,Who see the heart and the mind,Let me see Your vengeance on them;For to You I have committed my cause.
