Albert Barnes Commentary 1 Kings 20:17

"And the young men of the princes of the provinces went out first; and Ben-hadad sent out, and they told him, saying, There are men come out from Samaria." — 1 Kings 20:17 (ASV)

Ben-hadad sent out, and they told him - The Septuagint has a better reading: they sent and told the king of Syria.
