Jeremiah 6:27

I have set thee for a tower and a fortress among my people, that thou mayest know and try their way.

I have made you a tester of metals [and] a fortress among my people; that you may know and try their way.

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

A watch-tower I have given thee, Among My people a fortress, And thou knowest, and hast tried their way.

“I have appointed you to examine My people like ore, so you may know and try their ways.
