Charles Ellicott Commentary 2 Chronicles 18:3

"And Ahab king of Israel said unto Jehoshaphat king of Judah, Wilt thou go with me to Ramoth-gilead? And he answered him, I am as thou art, and my people as thy people; and [we will be] with thee in the war." — 2 Chronicles 18:3 (ASV)

And Ahab king of Israel. —This verse is essentially the same as 1 Kings 22:4. From this point the two narratives practically coincide. (See the Notes on 1 Kings 22).

To Ramoth-gilead —i.e., Ramoth of, or in, Gilead. Ramoth (“heights”), or Ramath or Ramah (“height”), was a common name in such a hilly country as Palestine. Kings adds, to the war.

And my people ... in the war —The symmetry of this part of the verse has been disregarded by the chronicler, in order to make Jehoshaphat express an apparently more definite assent to Ahab’s request. (Compare to Kings: “My people as thy people, my horses as thy horses” (kamônî kamôka, kĕ ‘ ammî kĕ ‘ ammbka, kĕsûsai kĕsûseika)). The Syriac reads: “And my horses as thy horses; and I will go with thee to the war.” Similarly the Arabic: “My horsemen as thy horsemen.”
