It happened, when he had come, that he blew a trumpet in the hill-country of Ephraim; and the children of Israel went down with him from the hill-country, and he before them.
Judges 3:29 is difficult to interpret for two reasons. First, the word translated "thousand" can also mean "military unit" (cf. Judges 20:10). Second, it is not clear whether the Israelites killed these Moabites as they tried to cross the Jordan on this occasion. Perhaps this was the total Moabite force that the Israelites killed in their war with Moab. In either case this was a great victory for Israel.
