'Allegiance' in the Bible

Don’t become obstinate now like your fathers did. Give your allegiance to Yahweh, and come to His sanctuary that He has consecrated forever. Serve the Lord your God so that He may turn His burning anger away from you,

He also rebelled against King Nebuchadnezzar who had made him swear allegiance by God. He became obstinate and hardened his heart against returning to Yahweh, the God of Israel.
