1 Samuel 10:7-8

And let it be, when these signs are come unto thee, that thou do as occasion serve thee; for God is with thee.

And thou shalt go down before me to Gilgal; and, behold, I will come down unto thee, to offer burnt offerings, and to sacrifice sacrifices of peace offerings: seven days shalt thou tarry, till I come to thee, and shew thee what thou shalt do.
