Charles Ellicott Commentary 1 Samuel 1:6

"And her rival provoked her sore, to make her fret, because Jehovah had shut up her womb." — 1 Samuel 1:6 (ASV)

And her adversary also provoked her sore. —Jealousy, grief, anger, malice, the many bitter fruits of this way of living, so different to God’s original appointment, here show themselves. The one sin of polygamy poisons the whole home life of the family, in all other respects apparently a quiet, Godfearing, orderly household.
