Genesis 18:12

Then Abraham fell on his face and laughed and said in his heart, “Will a son be born to a man one hundred years old? And will Sarah, who is ninety years old, bear a son?”

Then the King will desire your beauty. Because He is your Lord, bow down to Him.

But the son by the servant-woman had been born according to the flesh, while the son by the free woman through the promise.

By faith even Sarah herself received ability to conceive, even beyond the proper time of life, since she regarded Him faithful who had promised.

Do not neglect to show hospitality to strangers, for by this some have entertained angels without knowing it.

just as Sarah obeyed Abraham, calling him lord. You have become her children if you do good, not fearing any intimidation.
