'Verified' in the Bible

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

This was to fulfill and verify the words He had spoken, “Of those whom You have given Me, I have not lost even one.”

For these things took place to fulfill the Scripture, “Not a bone of His shall be broken.”

This will be the third time I am coming to you. "Every accusation must be verified by two or three witnesses."
