Keil & Delitzsch, on Judg 8:28

The history of Gideon is concluded in Jdg 8:28-32. - Jdg 8:28. The Midianites had been so humiliated that they lifted up their head no more, and the land of Israel had rest forty years "in the days of Gideon," i.e., as long as Gideon lived. Jdg 8:29-31 Before the account of his death, a few other notices respecting his family are introduced for the purpose of preparing the way for the following history of the doings of his sons, in which the sin of Gideon came to a head, and the judgment burst upon his house. "And Jerubbaal, the son of Joash, went and dwelt in his house." Both the word ויּלך, which simply serves to bring out the fact more vividly (see the remarks on Exo 2:1), and also the choice of the name Jerubbaal, merely serve to give greater prominence to the change, from the heat of the war against the Midianites to the quiet retirement of domestic life. Instead of accepting the crown that was offered him and remaining at the head of the nation, the celebrated Baal-fighter retired into private life again. In addition to the seventy sons of his many wives, there was a son born to him by a concubine, who lived at Shechem and is called his maid-servant in Jdg 9:18, and to this son he gave the name of Abimelech, i.e., king's father. את־שׁמו ויּשׂם is not the same as את־שׁמו קרא, to give a person a name, but signifies to add a name, or give a surname (see Neh 9:7, and Dan 5:12 in the Chaldee). It follows from this, that Abimelech received this name from Gideon as a cognomen answering to his character, and therefore not at the time of his birth, but when he grew up and manifested such qualities as led to the expectation that he would be a king's father. Jdg 8:32 Gideon died at a good old age (see Gen 15:15; Gen 25:8), and therefore also died a peaceful death (not so his sons; see Judg 9), and was buried in his father's grave at Ophrah (Jdg 6:11).
