2 Samuel 3:22-23

22David's men and Joab had attacked some of the enemy's towns. Now they were returning home. They brought with them a lot of things that they had taken from the enemy. By this time Abner had left Hebron because David had sent him away safely.

23When Joab and all his soldiers arrived in Hebron, people told him, ‘Ner's son Abner came to visit the king. The king sent him back home safely.’
