In Numbers 31, Moses is commanded to perform one more task before he died – to organise the attack on Midian. This attack was “the Lord’s vengeance on Midian”, for their role in causing Israel to sin with the daughters of Moab, back in Numbers 25. 12000 men of Israel were accompanied by Phinehas, the son of Eleazar the priest, along with vessels of the sanctuary. The battle resulted in no deaths among the Israelites.
It’s a gruesome account of one of Israel’s many battles, yet it serves as a reminder to us that God keeps His promises, both of grace and of vengeance. He promised Abraham that He would curse those that cursed Israel, and this battle against the Midianites is an example of that.
By contrast, we read in John 4 of the healing power of God’s word. It is “living water”, with the ability to become in us “a spring of water welling up to eternal life”, if we consume it regularly and let it affect our lives. God is seeking people to worship him in spirit and truth, to drink of living water and never thirst again.
