Jerubbaal in the Bible Encyclopedia - ISBE
jer-u-ba'-al, je-rub'-a-al (yerubba`al, "let Baal contend"):
The name given to Gideon by his father, Joash, and the people
in recognition of his destruction of the altar of Baal at
Ophrah (Jdg 6:32). For this name the form "Jerubbesheth" (2
Sam 1:21) was substituted after the analogy of "Ishbosheth"
and "Mephibosheth," in which bosheth, the Hebrew word for
"shame," displaced the word ba`al, no doubt because the name
resembled one given in honor of Baal.
See GIDEON.
