In the spring, when the kings normally went out to war, David sent out Joab, his servants, and all the Israelites. They destroyed the Ammonites and attacked the city of Rabbah. But David stayed in Jerusalem.
David said to the messenger, “Say this to Joab: ‘Don’t be upset about this. The sword kills everyone the same. Make a stronger attack against the city and capture it.’ Encourage Joab with these words.”
Shobi, Makir, and Barzillai were at Mahanaim when David arrived. Shobi son of Nahash was from the Ammonite town of Rabbah. Makir son of Ammiel was from Lo Debar, and Barzillai was from Rogelim in Gilead.
(Only Og king of Bashan was left of the few Rephaites. His bed was made of iron, and it was more than thirteen feet long and six feet wide! It is still in the Ammonite city of Rabbah.)
