🔼The name Jerubbaal in the Bible
There's only one man named Jerubbaal in the Bible, and he is better known as Gideon, the son of Joash the Abiezrite (Judges 6:11). When Israel was suffering from Midianite invasions, an angel of YHWH appeared to Gideon and instructed him to chop down the altar of Baal that night and the adjacent effigy of Asherah while he was at it (Judges 6:25).
When the locals arose and found their shrines wrecked, it didn't take them long to figure out who the culprit was. They marched over to Joash and demanded of him to surrender his son Gideon, in order to execute him. But Joash cleverly responded by saying that if Baal wants his revenge, it would be foolish to ruin his pleasure by killing Gideon before he could get to him. If Baal was truly a god, Baal would contend with Gideon, and if he were not, then Gideon would contend with Baal.
And so Joash named his son Jerubbaal, although after Jerubbaal's death the people went straight back to Baal and Baal-berith (Judges 8:33). The author of 2 Samuel 11:21, however, couldn't contain his disgust and edited the reference to Baal out of the name Jerubbaal and dubbed him Jerubbesheth.
