And Phinehas the son of Eleazar the priest said unto the children of Reuben, and to the children of Gad, and to the children of Manasseh, This day we perceive that the LORD is among us, because ye have not committed this trespass against the LORD: now ye have delivered the children of Israel out of the hand of the LORD.
Phinehas, son of Eleazar the priest, told the people of Reuben, Gad, and Manasseh that God is with us today because they didn't disobey Him. They saved the Israelites from God's punishment.
