'Humble' in the Bible

if my people, who belong to me, humble themselves, pray, seek to please me, and repudiate their sinful practices, then I will respond from heaven, forgive their sin, and heal their land.

He did not humble himself before the Lord as his father Manasseh had done. Amon was guilty of great sin.

He did evil in the sight of the Lord his God. He did not humble himself before Jeremiah the prophet, the Lord's spokesman.
