1-samuel 1:7

And as he did so year by year - As the whole family went up to Shiloh to the annual festivals, Peninnah had both sons and daughters to accompany her, 1 Samuel 1:4, but Hannah had none; and Peninnah took this opportunity particularly to twit Hannah with her barrenness, by making an ostentatious exhibition of her children.

Therefore she wept - She was greatly distressed, because it was a great reproach to a woman among the Jews to be barren; because, say some, every one hoped that the Messiah should spring from her line.

And as he did so ... - It should rather be "And so she did year by year, as often as she went up to the House of the Lord, so she provoked her." Though the verb is masculine, Peninnah must be the subject, because as often as SHE went up follows. The Vulgate has "they went up."

1:7 When she went - This circumstance is noted as the occasion of the contention, because at such times they were forced to more society with one another, by the way, and in their lodgings; whereas at home they had distinct apartments, where they might be asunder; and then her husband's extraordinary love and kindness was shewed to Hannah, whereby Peninnah was the more exasperated; then also Hannah prayed earnestly for a child, which hitherto she had done in vain; and this possibly she reproached her with. Did not eat - Being overwhelmed with grief, and therefore unfit to eat of the sacred food. Which they were not to eat in their mourning.
