What does Judges 12:9 mean?
While little is known about Ibzan, he stands in stark contrast to Jephthah in at least one way. Jephthah had one single child, a daughter, lost to him because of his rash vow to the Lord (Judges 11:30–31, 34–35). In comparison, Ibzan has thirty sons and thirty daughters.Ibzan also seems deeply committed to building alliances between his clan and others. This might include those inside and outside his own tribe. By strategically marrying each of his children to the children of other clans, Ibzan likely solidified and expanded his own political power. In addition, he would have increased the interconnectedness between the Israelites, giving them stronger unity against the outside nations around them.
Ibzan's term as judge over Israel lasted seven years, until his death (Judges 12:10).
