The explanation is accepted

30When Phinehas the priest, the leaders of the congregation, and the heads of the thousands of Israel who were with him heard the words that the sons of Reuben, the sons of Gad, and the sons of Manasseh spoke, it was good in their eyes.

31And Phinehas son of Eleazar the priest said to the sons of Reuben, and to the sons of Gad, and to the sons of Manasseh, “Today we know that Yahweh is among us, because you have not acted unfaithfully against Yahweh in this matter. Then you have delivered the sons of Israel from the hand of Yahweh.”
