Ahab was the seventh king of Israel. His wife was the infamous Jezebel, who exercised an evil influence over him. She persuaded him to add the worship of Baal to the calf-worship introduced by Jeroboam. Ahab was by Elijah that the country would suffer from severe draught if the cult of Baal was not removed from the land but not only was it a warning that Ahab ignored, he tried to have the prophet killed.
After three years of drought, Elijah challenged Ahab and the priests of Baal on Mount Carmel. The priests of Baal could not ignite a sacrifice despite fervent prayers; God, however, accepted the offering even after it had been soaked in water. The people, realizing who was the true God, turned to him.
Elijah then went to Ahab to deliver a message from God for the murder of Naboth, a plot that Jezebel had instigated because Naboth had refused to give the king his vineyard, which the king wanted.
"Go down to meet Ahab king of Israel, who rules in Samaria. He is now in Naboth's vineyard, where he has gone to take possession of it. Say to him, 'This is what the LORD says: Have you not murdered a man and seized his property?' Then say to him, 'This is what the LORD says: In the place where dogs licked up Naboth's blood, dogs will lick up your blood-yes, yours!' "
(1 Kings 21:18-19)
The warning made Ahab go into deep repentance, which resulted in the postponement of the prophecy. He then undertook three campaigns against Ben-hadad, the king of Damascus. In the first two campaigns, he gained a complete victory over Ben-hadad, who fell into his hands. He later released the king on the condition that he would restore all the cities of Israel he held.
After three years of peace, Ahab went to war again with Ben-hadad against the warnings of the prophet Micaiah that it would lead to ruin. Allying himself with Jehoshaphat, King of Judah, he assaulted the city of Ramoth-gilead. Ahab went into the battle disguised, hoping that the ruse would escape the notice of his enemies, but was killed by a stray arrow.
When the blood on his chariot was washed off at a pool in Samaria, the dogs licked up his blood - just as Elijah had prophesied.
Ahab reigned twenty-three years. His son Ahaziah succeeded him on the throne.
