Smith’s Bible Dictionary

Gera

(a grain), one of the "sons," i.e. descendants, of Benjamin. (Genesis 46:21) Gera, who is named, (Judges 3:15) as the ancestor of Ehud, and in (2 Samuel 16:5) as the ancestor of Shimei who cursed David, is probably also the same person (though some consider them different persons).
