Several ancient textual witnesses, including some LXX mss and the Vulgate, support the reading “Moses” (מֹשֶׁה, mosheh) here. Many Hebrew mss have a nun (נ) suspended above the name between the first two letters (מנשׁה), suggesting the name Manasseh (מְנַשֶּׁה, mÿnasheh). This is probably a scribal attempt to protect Moses’ reputation. For discussion, see
G. F. Moore, Judges (ICC), 401-2.
