This Strong's number (H439) represents another occurrence of the short form of Elijah's name (Elijjah, אֶלְיָה), the same as H438 — "My God is Yahweh." The distinction in Strong's numbering reflects a slightly different textual context or manuscript tradition. Both H438 and H439 refer to the great prophet Elijah the Tishbite, one of the most dramatic figures in the entire Old Testament, whose ministry spanned the reigns of Ahab and Ahaziah in the northern kingdom.
Elijah stands at the intersection of the Law and the Prophets as the ultimate prophetic prototype. His prayer brought drought; his prayer brought rain (James 5:17–18). He raised the dead (1 Kings 17:17–24), called down fire from heaven (1 Kings 18:38), and was fed by angels in the wilderness (1 Kings 19:5–8). The New Testament understanding of Elijah's ministry is not merely historical but eschatological — John the Baptist came "in the spirit and power of Elijah" (Luke 1:17), and Elijah appeared at the Transfiguration representing all the prophets. James holds him up not as a superhuman but as a model: "Elijah was a human being, even as we are." His power came from prayer, not from personal greatness. God can do with ordinary praying people what He did through Elijah.
