2 Samuel 2:27-28
27-28"As God lives," said Joab, "if you hadn't spoken up, we'd have kept up the chase until morning!" Then he blew the ram's horn trumpet and the whole army of Judah stopped in its tracks. They quit chasing Israel and called off the fighting.
29Abner and his soldiers marched all that night up the Arabah Valley. They crossed the Jordan and, after a long morning's march, arrived at Mahanaim.
