Ruler Mentioned in the Bible by name

Ahaziah

And Ahab slept with his fathers, and Ahaziah (Hebr. Achazijaho), his son, reigned in his place.

At that time, Ahaziah (Hebr. Achazijaho), son of Ahab, said to Jehoshaphat, "Let my servants go with your servants on the ships." But Jehoshaphat would not.

Ahaziah, son of Ahab, began to reign over Israel in Samaria in the 70th year of Jehoshaphat, king of Judah, and he reigned two years over Israel.

And Ahaziah (Hebr. Achazjaho) fell through the latticework of his upper room in Samaria (Hebr. Shomron) [capital of the Northern Kingdom, present-day Sebastia] and became ill.
[Excavations in the city of Samaria have shown that the royal palace had two floors. It was common to have an open courtyard in the middle. The grating could either be a railing or a wooden lattice covering a courtyard.] So he [Ahaziah] sent messengers and said to them, "Go and ask Baal-Zebub (Baal-Zebub), the god of Ekron, if I will recover from this illness."
[Baal-Zebub means "Lord of the Flies." Ekron was the northernmost of the five major Philistine cities bordering Israel, see Josh. 13:3. From Samaria down to Ekron, it was about 70 miles.]

The rest of the acts of Ahaziah that he did, are they not written in the chronicles of the kings of Israel?

After that, Jehoshaphat, king of Judah, made a covenant with Ahaziah, king of Israel, even though Ahaziah was wicked.

Then Eliezer, the son of Dodavahu of Mareshah, prophesied against Jehoshaphat, saying, "Because you have made a covenant with Ahaziah, the Lord (Yahweh) will bring your enterprise to nothing." And the ships were wrecked so that they could not go to Tarshish.
