New Defender's Study Bible Notes
7:7 three hundred men that lapped. God first had Gideon reduce his army by sending 22,000 men who were fearful and afraid back home (Judges 7:3), leaving only 10,000 to face the 135,000 Midianites (Judges 8:10). Then it was further diminished to only three hundred men who did not bow “down upon his knees to drink water” but instead “lappeth of the water...as a dog lappeth” (Judges 7:5-6). No explanation for this choice is given, but it probably was based on alertness, just as the first was based on courage. The men may have drunk from cupped hands rather than directly from the brook surface.
7:20 sword of the LORD. This passage is widely known as a key motto of the Christian laymen’s organization known as the Gideons, with their local chapters known as camps and with their strong emphasis on the Scriptures as the sword of the Spirit, able to conquer the enemy and win victories for the Lord. The victory was a great testimony both to the remarkably effective victory stratagem devised by Gideon and the providential working of God.
