2 Kings 1:17

2 Kings 1:17 Meaning and Commentary

2 Kings 1:17

So he died, according to the word of the Lord which Elijah had
spoken
How long or how soon after this is not said; however, he died of the sickness, and on the bed to which he went up, as he said:

and Jehoram reigned in his stead:
who was another son of Ahab, and brother of Ahaziah, ( 2 Kings 3:1 ) , in the second year of Jehoram the son of Jehoshaphat king of Judah; but as he must begin his reign in the nineteenth, or in the latter end of the eighteenth year of Jehoshaphat, see ( 1 Kings 22:51 ) ( 2 Kings 3:1 ) and Jehoshaphat reigned in all twenty five years, ( 1 Kings 22:42 ) , he must live and reign after this six or seven years; this therefore is to be reconciled by observing, that this son of Jehoshaphat was made viceroy, or was taken into partnership in the throne by his father when he went with Ahab to Ramothgilead; and it was in the second year of this his reign with his father that the other Jehoram began his:

because he had no son;
that is, Ahaziah, wherefore his brother reigned in his stead.

2 Kings 1:17 In-Context

15 Then the angel of the LORD said unto Elijah, Go down with him; do not be afraid of him. And he arose and went down with him unto the king.

16 And he said unto him, Thus hath the LORD said, Forasmuch as thou hast sent messengers to enquire of Baalzebub, the god of Ekron, peradventure is there no God in Israel to enquire of his word? Therefore, thou shalt not come down off that bed on which thou art gone up, but shalt surely die.

17 So he died according to the word of the LORD which Elijah had spoken. And Jehoram (son of Ahab) reigned in his stead, in the second year of Jehoram, the son of Jehoshaphat, king of Judah, because Ahaziah had no son.

18 Now the rest of the acts of Ahaziah which he did, are they not written in the book of the chronicles of the kings of Israel?
