Jerome : (Verse 10 and 11.) And Zilpah, the maid of Leah, bore Jacob a son, and Leah said, 'In fortunate circumstances,' and she called his name Gad. Where we have placed ourselves, in fortunate circumstances, and in Greek it is said ἐν τύχῃ, which can be translated as 'event.' In Hebrew, it is Bagad (), which Aquila interprets as 'girdle' or 'belt.' But we can say 'in readiness.' For Ba can sound like the preposition 'in,' and gad means 'coming.' Therefore, from the event or readiness, the son of Zilpah, Gad, was called. Sequitur: — Hebrew Questions on Genesis
