Jeremiah 6:27-29

Wycliffe Bible

²⁷ I gave thee to be a strong prover in my people, and thou shalt know, and prove the way of them. (I gave thee to be a strong assayer, or a strong tester, of my people, and thou shalt know, and prove their ways.)

²⁸ All these princes bowing away, going guilefully, be (like) metal and iron; all be corrupt. (All these people turning away, doing deceitfully, be made hard like metal and iron; they all be corrupt.)

²⁹ The bellow failed, lead is wasted in the fire, the weller welled in vain (the welder welded in vain); for the malices of them be not wasted.
