1 Samuel 25:13

Then everyone who was in distress, and everyone who was in debt, and everyone who was bitter of soul, gathered to him; and he became a commander over them. Now there were about four hundred men with him.

Then David and his men, about six hundred, arose and departed from Keilah, and they went wherever they could go. Now it was told to Saul that David had escaped from Keilah, so he ceased going out in pursuit.

So David arose and crossed over, he and the six hundred men who were with him, to Achish the son of Maoch, king of Gath.

Now all his servants passed on beside him, all the Cherethites, all the Pelethites, and all the Gittites, six hundred men who had come with him from Gath, passed on before the king.

A gentle answer turns away wrath, But a harsh word stirs up anger.
