Amos 3:7: Surely the Lord GOD will do nothing, but he revealeth his secret unto his servants the prophets.
Contradiction with Proverbs 11:13
This verse states that a talebearer reveals secrets, contrasting with the subtlety and hidden nature of the betrayal in John 13:21.

Contradiction with Matthew 10:26
