Matthew Henry Presbyterian @wholebiblehenry

We have here the bad consequences of that strange marriage which Jacob made with the two sisters. Here is, I. An unhappy disagreement between him and Rachel (Gen 30:1, Gen 30:2), occasioned, not so much by her own barrenness as by her sister's fruitfulness.

And Bilhah, Rachel's maid, conceived again,.... Soon after the birth of her first child: and bare Jacob a second son; this was his sixth son, but the second by Bilhah.

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.
