Concise Bible Dictionary:
1. Gideon’s youngest son who escaped the massacre by Abimelech. He boldly declared the parable “The Reign of the Bramble” in the hearing of the men of Shechem (Judg. 9:5-21, 57).
2. Son and successor of Uzziah, or Azariah, king of Judah: he reigned sixteen years (B.C. 758-742), besides ruling during the leprosy of his father. Jotham did that which was right in the sight of the Lord. He erected the high gate of the house of the Lord, and built much on Ophel; also in the mountains of Judah he built cities, castles, and towers. He conquered the Ammonites, and for three years they paid him tribute. He became mighty because he prepared his way before the Lord his God (2 Kings 15:5-38; 2 Chron. 27:1-9; Isa. 1:1; Isa. 7:1; Hos. 1:1; Mic. 1:1). Called JOATHAM in Matthew 1:9.
3. Son of Jandai, a descendant of Judah (1 Chron. 2:47).
