1CH 20:1

1 [In that region], kings usually went [with their armies] to fight [their enemies] ◄in the springtime/when the cold season ended►. But that year, David [did not do that. Instead, he] stayed in Jerusalem, and he sent [his commander] Joab [to lead the army]. Joab took his troops. They [crossed the Jordan River and] ruined the land of the Ammon people-group. Then they went to Rabbah, [the capital city,] and surrounded it. David stayed in Jerusalem [for a while. But later he took more troops and went to help] Joab. Their armies attacked Rabbah and destroyed it.
