1. Seeking to find out the truth (10-20)

The 2 1/2 tribes had built an imposing altar. Israel assumed it was used as a place for sacrifice. They sent a group to find the truth. They warned them of what would happen if they set up alternatives to worship. They gave them a chance to explain themselves. They heard rumors and were ready to fight, but they were still ready to investigate. The truthfulness and justice of God was revealed.

2. God revealed the truth (21-34)

The eastern tribal leaders stated their motive. They feared that, as time passed, the other tribes would reject them, stating that they have no part in the Lord. This might have caused future generations to stop fearing the Lord (24-25). The altar was a witness that the eastern tribes are indeed part of Israel. God was with them and saved them from war.
