2 Kings 8:19

“Yet the Lord would not destroy Judah for David his servant’s sake, etc.] Not for his merits, but for the mercy he assured him of: as he promised him to give to him always a light, [and] to his children; or a kingdom, as the Targum; therefore he would not utterly destroy the tribe, nor suffer the sceptre or government to depart from it till the Messiah came, (see <19D211>Psalm 132:11,17).”

“The passage is parenthetic, resuming the history of the kingdom of Judah from 1 Kings 22:50. 2 Kings 8:16 The opening words are - “In the fifth year of Joram, son of Ahab, king of Israel, and of Jehoshaphat, king of Judah;” but they contradict all the other chronological notices of Jehoshaphat 1 Kings 22:42, 1Ki 22:51; 2 Kings 3:1; 2 Chronicles 20:31, which give him a reign of at least twenty-three years.

A light - A son and successor. 4 Kings (2 Kings) 8:29”

“8:19 Despite Jehoram’s wickedness, God did not destroy Judah but honored his covenant with David (2 Sam 7:11-16). • The Lord had promised to preserve David’s descendants on the throne of Judah as a shining . . . lamp of God’s grace (1 Kgs 11:36). God’s promises to David ultimately find fulfillment in Jesus (Ezek 34:23-31), the light of the world (John 4:1-5).”
