Verses 10, 11. - And Zilpah Leah's maid bare Jacob a son. And Leah said, A troop cometh. בָּגָד, for בְּגָד, in or with good fortune; ἐν τύχη (LXX.); feliciter, sc. this happens to me (Vulgate), a translation which has the sanction of Gesenius, Furst, Rosenmüller, Keil, Kalisch, and other content authorities - the Keri, whith is followed by Onkelos and Syriac, reading בָּא גָד, fortune cometh. The Authorised rendering, supported by the Samaritan, and supposed to accord better with Genesis 49:19, is approved by Calvin, Ainsworth, Bush, and others. And she called his name Gad - i.e. Good Fortune.

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.And Zilpah, Leah's maid, bore Jacob a son. For it seems he consented to take her to wife at the motion of Leah, as he had took Bilhah at the instance of Rachel; and having gratified the one, he could not well deny the other; and went in to her, and she conceived, though neither of these things are mentioned, but are all necessarily supposed.
