Amasa

Amasa son of Hadlai was one of the Ephraimite leaders who, following a prophetic rebuke by Oded, convinced the Israelite army to release the Judahite captives they had taken in the war between Israel and Judah during Pekah's reign (2 Chronicles 28:12). This act of mercy—clothing, feeding, and returning the captives—is one of the most striking humanitarian episodes in Chronicles. A more famous Amasa was the son of Abigail (David's sister) and a general appointed by Absalom during the rebellion; later David appointed him to replace Joab, but Joab murdered him (2 Samuel 17:25; 19:13; 20:9–10). These are likely two different individuals.
