The men were grieved. Literally, “made themselves furious.” The second expression, “they were very wroth,” reads literally, “it burned to them greatly.” Their passionate anger was beyond control (cf. 1 Sam. 15:11; 2 Sam. 19:43). How the men must have felt can be understood from the fact that modern Arabs feel more dishonored by the seduction of a sister than by the infidelity of a wife. A man, they say, may divorce his wife, and she is then no longer his, but a sister or daughter ever remains a sister or daughter.
It was therefore proper that they should be grieved and only natural that they should be angry. Their own honor was bound up with that of their sister. They were not so much concerned, however, with the sin committed against God as with the shame that had come upon their family. In this attitude toward the affair lay the source of their great mistake in dealing with it (Gen. 49:7).
Wrought folly. “To work folly” became a standing phrase for crimes involving honor, especially for the sins of the flesh (Deut. 22:21; Judges 20:10; 2 Sam. 13:2; etc.), but for others also (Joshua 7:15).
In Israel. The name Israel is here applied for the first time to Jacob’s household. Later it became the unusual designation for the nation. Some commentators, pointing out that the sons of Jacob were not called either Israel or Israelites until long afterward, think the phrase “in Israel” should be translated “against Israel.” This is grammatically permissible, and would imply that the affair was a crime against Jacob, who had become Israel, “a prince of God.”
