1 Samuel 22:5

And the prophet Gad said unto David, Abide not in the hold; depart, and get thee into the land of Judah. Then David departed, and came into the forest of Hareth.

Ver. 5. And the prophet Gad said unto David.] It was no small comfort to distressed David to have about him a prophet, called elsewhere David's seer, 1Ch 21:9 and afterwards also the high priest with the ephod, by whom he might and did inquire of God upon all occasions. 1 Samuel 23:2 ; 1Sa 23:4

Depart, and get thee into the land of Judah.] Where thou mayest be in action, and do some good to thy country. God is a pure act, and he willeth that all his should be active, "and run with patience the race that is set before them." Heb 12:2
