She called his name Gad - This has been variously translated. גד gad, may signify a troop, an army, a soldier, a false god, supposed to be the same as Jupiter or Mars; for as Laban appears to have been, if not an idolater, yet a dealer in a sort of judicial astrology, (see Genesis 31:19), Leah, in saying בגד bagad, which we translate a troop cometh, might mean, By or with the assistance of Gad - a particular planet or star, Jupiter possibly, I have gotten this son; therefore she called him after the name of that planet or star from which she supposed the succor came. See note on Genesis 31:19. The Septuagint translate it εν τυχη, with good fortune; the Vulgate, feliciter, happily; but in all this diversity our own translation may appear as probable as any, if not the genuine one, בא גד ba gad, for the keri, or marginal reading, has it in two words, a troop cometh; whereas the textual reading has it only in one, בגד bagad, with a troop. In the Bible published by Becke, 1549, the word is translated as an exclamation, Good luck!

And Leah said, a troop cometh,.... A troop of children, having bore four herself, and now her maid another, and more she expected; or the commander of a troop cometh, one that shall head an army and overcome his enemies; which agrees with the prophecy of Jacob, Genesis 49:19,

and she called his name Gad: which signifies a "troop", glorying in the multitude of her children, that she had or hoped to have.

And Leah said, {d} A troop cometh: and she called his name Gad.

(d) That is, God increases me with a multitude of children for so Jacob explains this name Gad Ge 49:19.

Gad: that is, A troop, or, company

30:1-13 Rachel envied her sister: envy is grieving at the good of another, than which no sin is more hateful to God, or more hurtful to our neighbours and ourselves. She considered not that God made the difference, and that in other things she had the advantage. Let us carefully watch against all the risings and workings of this passion in our minds. Let not our eye be evil towards any of our fellow-servants, because our Master's is good. Jacob loved Rachel, and therefore reproved her for what she said amiss. Faithful reproofs show true affection. God may be to us instead of any creature; but it is sin and folly to place any creature in God's stead, and to place that confidence in any creature, which should be placed in God only. At the persuasion of Rachel, Jacob took Bilhah her handmaid to wife, that, according to the usage of those times, her children might be owned as her mistress's children. Had not Rachel's heart been influenced by evil passions, she would have thought her sister's children nearer to her, and more entitled to her care than Bilhah's. But children whom she had a right to rule, were more desirable to her than children she had more reason to love. As an early instance of her power over these children, she takes pleasure in giving them names that carry in them marks of rivalry with her sister. See what roots of bitterness envy and strife are, and what mischief they make among relations. At the persuasion of Leah, Jacob took Zilpah her handmaid to wife also. See the power of jealousy and rivalship, and admire the wisdom of the Divine appointment, which joins together one man and one woman only; for God hath called us to peace and purity.
