Genesis 30:9-13

(9-13) Leah... took Zilpah... — By ceasing to bear, Leah had lost her one hold upon her husband’s affection, and to regain it she follows Rachel’s example. The struggle of these two women for the husband gives us a strange picture of manners and morals, but must not be judged by our standard. Leah herself regards the bestowal of her handmaid upon Jacob as a deserving act of self-sacrifice (Genesis 30:18). The names, moreover, which she gives to Zilpah’s children show that the happier frame of mind to which she had attained when she called her fourth son “Judah,” praise, remained unbroken. On the birth of the first, she says, “With good luck!” and calls his name “Gad,” that is, luck. The Jews read, in their synagogue, Luck cometh, whence the rendering of the Authorised Version, “A troop cometh;” but there is no justification for the change. With regard to the meaning of the word “Gad,” all the Versions render it prosperity, good fortune. Nor is the Samaritan, as has been alleged, an exception; for though the worthless Latin translation of it has “a troop cometh,” the Samaritan itself has with good luck. In Isaiah 65:11 we find Gad used as the name of an idol. Zilpah’s other son is called Asher, that is, happy, in Latin Felix, and Leah says, “With my happiness,” using just the same turn of speech as before. The first child came bringing her good luck; the second brought her happiness.
