Genesis 29:33

And she conceived again, and bare a son,.... As soon as she well could. The Jews x have a notion, that Leah brought forth her sons at seven months' end:

and said, because the Lord hath heard that I [was] hated; or less loved than her sister:

he hath therefore given me this [son] also; to comfort her under the trial and exercise, and engage her husband's love the more unto her:

and she called his name Simeon: which signifies "hearing", and answers to the reason of her having him as she concluded.
