What is the significance of the phrase “Go in this thy fortress, and thou shalt save Israel from the hand of Midian” (Judges 6:14)? Encouraged by the angel to rally an army and confront the enemy, Gideon responded, “And if the Lord be with us, why have we found all these evils? And where are all His miracles, which our fathers told us, saying, ‘The Lord brought us out of Egypt? And now the Lord hath cast us off, and delivered us into the hand of Midian’” (Judges 6:13).
