According to the Old Testament, who had "too many" men in his army?
The answer to this question can be found in Judges, Chapter 7. The person who had too many men in his army was Gideon.
God had called Gideon to raise an army to defeat the Midianites. He got 32,000 men to join. But God felt that this was too many because the Israelites would feel that they had defeated the Midianites on their own, not through God's strength. So God had Gideon send 22,000 of the men away. But that was still too many and God had Gideon take his men to a river to drink. All those who knelt to drink were sent away and only the 300 who brought water to their mouths in their hands and lapped it up were kept.
