Judges 6:11-26 — The obvious thing to comment on is the conflation of the Angel of the LORD and the LORD in this passage. The Angel of the LORD appears and speaks to Gideon as one distinct from the LORD (vv. 11-13, 20-21) but then with no hint that the LORD has shown up and the angel of the LORD has gone, the LORD himself appears and speaks to Gideon (vv. 14, 16, 23, 25-26). The narrative presents the Angel of the LORD as being both distinct from the LORD and the LORD himself. He even receives the sacrifice offered in vv. 20-21, although I’ve heard certain Unitarians argue that he didn’t. I don’t know what text they’re reading, but he touches the sacrifice and it’s consumed by fire, so that counts.
There’s also something to be said for v. 16. The LORD says that he will be with Gideon and his clan and that they shall strike the Midianites as “one man.” Their power is obviously in the LORD but there’s also power in unity and being in unison. It reminds me of Acts 2 on the day of Pentecost when the church was together on one accord and they were baptized with the Holy Spirit.
Judges 7 — How’s the saying go, “God plus one equals a majority”? This is a perfect example. I can tell you from personal experience that God has done so much in my life that it would have been impossible for me to do on my own. There have been times when I’ve been in financial crunches and God has shown up at the last possible minute and provided the necessary funds to take care of what needed to be taken care of. I’m convinced that he’s worked like this so that I could never boast and give anyone else the credit. Obviously this isn’t the same as going to war, but I think the principle is the same. God can beat all odds.
Joshua 8 — Same ol’ story. The LORD shows himself mighty and blesses Israel and they forsake him for idols. Rinse and repeat.
