The Greek form Asa (Ἀσά) represents the Hebrew name Asa (אָסָא), meaning "healer" or possibly "created by God." In the New Testament, Asa appears in Matthew's genealogy of Jesus Christ — one of the kings of Judah in the royal line leading to the Messiah.
Asa was the third king of Judah and one of the few kings described as doing "what was good and right in the eyes of the LORD" (2 Chronicles 14:2). He began his reign with sweeping religious reform — removing foreign altars, smashing sacred stones, and cutting down Asherah poles. When Ethiopia's vast army attacked, Asa cried out to God: "LORD, there is no one like you to help the powerless against the mighty" (2 Chronicles 14:11) — and God gave him a decisive victory. His appearance in Matthew 1:7 places him in the messianic line, reminding readers that Christ comes through imperfect but covenant-keeping people, and that God's faithfulness spans generations.
