⁷  Let it be, when these signs are come to you, that you do as occasion shall serve you; for God is with you.

⁸  You shall go down before me to Gilgal; and, behold, I will come down to you, to offer burnt offerings, and to sacrifice sacrifices of peace-offerings: seven days shall you wait, until I come to you, and show you what you shall do.

⁹  It was so, that when he had turned his back to go from Samuel, God gave him another heart: and all those signs happened that day.

¹⁰  When they came there to the hill, behold, a band of prophets met him; and the Spirit of God came mightily on him, and he prophesied among them.
