Genesis 20:18 Meaning and Commentary

Genesis 20:18

For the Lord had fast closed up all the wombs of the house of
Abimelech
With large tumours probably, so that they could not cohabit with their husbands and conceive; nor could those that had conceived bring forth: and this disorder they were smitten with, because of Sarah Abraham's wife;
who was taken into the house of Abimelech, in order to be his; to rebuke and punish for which, and to convince of the evil of it, and cause to abstain from it, this disorder was inflicted on them.
