I am strong because my Lord goes with me

Deuteronomy 31:6-7

“Be strong and courageous. Don’t be afraid or scared of them; for the LORD your God himself is who goes with you. He will not fail you nor forsake you.” Moses called to Joshua, and said to him in the sight of all Israel, “Be strong and courageous, for you shall go with this people into the land which the LORD has sworn to their fathers to give them; and you shall cause them to inherit it.”
