1 Samuel 10:7-9

7And let it be, when these signs have come to thee, that thou do as occasion shall serve thee; for God is with thee.12 8And thou shalt go down before me to Gilgal; and, behold, I will come down to thee, to offer burnt offerings, and to sacrifice sacrifices of peace offerings: seven days shalt thou tarry, till I come to thee, and show thee what thou shalt do.

9And it was so, that when he had turned his back to go from Samuel, God gave him another heart: and all those signs came to pass that day.34
