Called she his name Dan - Because she found God had judged for her, and decided she should have a son by her handmaid; hence she called his name דן dan, judging.

And Rachel said,.... As soon as she heard that Bilhah had bore a son:

God hath judged me: and hereby testified his approbation, as she understood it, of the step she had took in giving her maid to her husband, and she was justified in what she had done:

and hath also heard my voice: of prayer; she had prayed to God that her maid might have a child, or she have one by her:

and hath given me a son; whom she reckoned her own, Bilhah being her servant, and so her children born of her, hers; or whom she adopted and called her own, and therefore took upon her to give it a name, as follows: and here let it be observed, that she looked upon this child as a gift of God, as the fruit of prayer, and as in mercy to her, God dealing graciously with her, and taking her part, and judging righteous judgment:

therefore called she his name Dan; which signifies "judgment"; the reason of it lies in the first clause of the verse.

And Rachel said, God hath judged me, and hath also heard my voice, and hath given me a son: therefore called she his name Dan.

Dan: that is, Judging

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.
