Abijah was the second King of Judah (911-908 BC). He was the son of King Rehoboam and Maacah, the grand-daughter of Absalom.
He was a sinner as was his father, and his heart was not right with God. However, in a battle with Israel, he defies Jeroboam's powerful army and tells the people of Israel "do not fight against the Lord God of your fathers, for you will not succeed." God used Abijah and the men of Judah to turn the tide of the battle against King Jeroboam and the army of Israel, defeating Israel and capturing the cities of Bethel, Jeshanah, and Ephron.
Abijah's reign lasted three years, he had 14 wives, and 22 sons and 16 daughters. When Abijah died, he was buried in Jerusalem, and his son, Asa, became the new king of Judah.
The story of Abijah is found in 1 Kings 15:1-8 and in 2 Chronicles, chapter 13.
