Mattot means “the tribes,” but also has very interesting secondary meanings of “staff, scepter, rod, branch,” all of which seem relevant here. The portion opens with a discussion on the need to fulfill valid oaths to Abba YHWH to the letter-valid meaning that the oath is not contradictory to Abba YHWH’s laws or pronouncements. Various examples and applications of this principle follow. Then it is time to actually go to war against Midian. It is interesting that the previous portion had Israel get ready for this mentally, by totally changing their attitude and then Abba YHWH says, “Now is the time.” Midian is crushed and defeated completely.
