Moses has announced his impending demise (vs. 2) and promises Yahweh’s continued presence (vss. 3-5). Then Moses appeals for courage and confidence (vs. 6). The Israelites had experienced victory against Shilon and Og (Deut. 2:26-37; 3:1-11). Based upon the experience of their victory, they could advance into the promised land in the certain knowledge of further victories through Yahweh’s strength. They are urged to be strong and be courageous (vs. 6) because their strength and courage would come not from confidence in their own abilities, but from confidence Yahweh would keep His promise to deliver victory. Yahweh shows His loyalty love of keeping His covenant relationship and promise to a chosen people by prevailing in their victory (vs. 6).
