Did evil again. — Literally, “added to do evil.” We find this Hebraism even in the New Testament. “He added (prosetheto) to send” (Luke 20:11-12).
Evil. — Literally, the evil, with special reference to idolatry, as in Judges 2:11, &c.
Strengthened Eglon the king of Moab. — See this event referred to by the prophet Samuel, in 1 Samuel 12:9. Eglon was a successor of Balak. We have seen that Rishathaim is probably a term of hatred or scorn; is the name Eglon due to the same tendency? It may be so, since Eglon means “a fat bullock” (comp. Psalms 22:12; Amos 4:1).
