The statement "This verb occurs only here in Judges, but it occurs in the name of Gideon." needs the clarification from Dr Block's commentary: namely, "In v. 6 the Israelites’ sorrow over the loss of their brother Benjamin is expressed with a direct quotation (lit.): “Today one tribe has been hacked off from Israel.” Although the name of Gideon, “Hacker,” derives from the same root, this is the only occurrence of the verb gādaʿ in the book." [Daniel Isaac Block, Judges, Ruth, vol. 6, The New American Commentary (Nashville: Broadman & Holman Publishers, 1999), 572. ]
