The NET gives the following information about the list of names found in 1 Samuel 12:11:
In the ancient versions there is some confusion with regard to these names, both with regard to the particular names selected for mention and with regard to the order in which they are listed. For example, the LXX has “Jerub-Baal, Barak, Jephthah, and Samuel.” But the Targum has “Gideon, Samson, Jephthah, and Samuel,” while the Syriac Peshitta has “Deborah, Barak, Gideon, Jephthah, and Samson.”
The KJV and NASB following the MT seemingly matching the LXX, but instead of Barak they have someone named Bedan. In that case it seems preferable to go with Barak since it mentions Sisera in verse 9 and since there's nobody really named Bedan elsewhere in the OT. As for the rest of the list, is preference given usually to the LXX? Or how would one decide who is listed when putting together a translation?
