1 Samuel 10:6-10

6And the Spirit of Jehovah will come upon thee, and thou shalt prophesy with them, and shalt be turned into another man.

7And it shall be, when these signs shall come to thee, thou shalt do as thy hand shall find; for 1God is with thee.

8And thou shalt go down before me to Gilgal; and behold, I will come down to thee, to offer up burnt-offerings, [and] to sacrifice sacrifices of peace-offerings: seven days shalt thou wait, until I come to thee and inform thee what thou shalt do.

9And it was [so] that when he turned his back to go away from Samuel, 2God gave him another heart; and all those signs came to pass that day.

10And when they came thither to the hill, behold, a company of prophets met him; and the Spirit of 3God came upon him, and he prophesied among them.
