In 1 Kings 1:5, Adonijah exalts himself and prepares to be king, confirming Bathsheba's claim that he is already reigning.

In 1 Kings 1:11, Nathan first tells Bathsheba that Adonijah has made himself king, setting up her approach to David.

In 1 Kings 1:24, Nathan echoes Bathsheba's alarm, asking if David authorized Adonijah's coronation — reinforcing the same plot point.

In 1 Kings 1:27, Nathan questions David about Adonijah's coronation, just as Bathsheba did — both seek David's clarification.

In 2 Samuel 15:10, Absalom similarly proclaims himself king in Hebron — Adonijah's usurpation mirrors his brother's earlier rebellion.
