'Try' in the Bible

I have made thee a trier and a fortress among my people; that thou mayest know and try their way.

Therefore thus saith Jehovah of hosts, Behold, I will melt them, and try them; for how else'should I do, because of the daughter of my people?

I, Jehovah, search the mind, I try the heart, even to give every man according to his ways, according to the fruit of his doings.
