'Verified' in the Bible

and bring your youngest brother to me, in order that your words be verified, and that ye may not die. And they did so.

And now, O God of Israel, let thy words, I pray thee, be verified, which thou hast spoken unto thy servant David my father.

And now, Jehovah, God of Israel, let thy word be verified which thou hast spoken unto thy servant David.

For in this is verified the true saying, It is one who sows and another who reaps.
