And the Lord said to me, Do not fear him, for I have given him and all his people and his land into your hand; and you shall do to him as you did to Sihon king of the Amorites, who lived at Heshbon.

Deuteronomy 03:02 (AMP)

Biblical Truth: Be encouraged by previous victories over fear in order to build up your confidence to trust in Him the next time, for God is God.
