2 Samuel 20:4-6

4Then the king told Amasa, “Mobilize the army of Judah within three days, and report back at that time.”

5So Amasa went out to notify Judah, but it took him longer than the time he had been given.

6Then David said to Abishai, “Sheba son of Bicri is going to hurt us more than Absalom did. Quick, take my troops and chase after him before he gets into a fortified town where we can’t reach him.”
