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.

Genesis 20:18 In-Context

16 Forsooth Abimelech said to Sarah, Lo! I gave a thousand pieces of silver to thy brother; this shall be to thee into (a) covering of (the) eyes, to all men that be with thee; and whither ever thou goest, have thou mind that thou art taken. (And Abimelech said to Sarah, Lo! I have given a thousand pieces of silver to thy brother; this shall be proof to all thy own people that thou art guiltless; but wherever thou goest, remember that thou art already taken.)

17 Soothly for Abraham prayed, God cured Abimelech, and his wife, and handmaids, and they childed; (And because Abraham prayed to God, God cured Abimelech, and his wife, and his slave-girls, and they gave birth;)
