'Allegiance' in the Bible

From the Benjaminites, the relatives of Saul: 3,000 (up to that time the majority of the Benjaminites maintained their allegiance to the house of Saul).

All the leaders and the mighty men, and all of King David’s sons as well, pledged their allegiance to King Solomon.

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.

By Myself I have sworn;Truth has gone from My mouth,a word that will not be revoked:Every knee will bow to Me,every tongue will swear allegiance.

For when you were slaves of sin, you were free from allegiance to righteousness.
