Jeremías 6

Te he constituido en mi pueblo como probador, como fortaleza; tú conocerás y examinarás su proceder.

Por fortaleza te he puesto en mi pueblo, por torre: conocerás pues, y examinarás el camino de ellos.

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.
