Genesis 21:1

"The words of the LORD are pure words: as silver tried in a furnace of earth, purified seven times."

"And he said, I will certainly return unto thee according to the time of life; and, lo, Sarah thy wife shall have a son. And Sarah heard it in the tent door, which was behind him."

"Is any thing too hard for the LORD? At the time appointed I will return unto thee, according to the time of life, and Sarah shall have a son."

"And God said, Sarah thy wife shall bear thee a son indeed; and thou shalt call his name Isaac: and I will establish my covenant with him for an everlasting covenant, and with his seed after him."

"But he who was of the bondwoman was born after the flesh; but he of the freewoman was by promise."

"Heaven and earth shall pass away, but my words shall not pass away."

"And the LORD visited Hannah, so that she conceived, and bare three sons and two daughters. And the child Samuel grew before the LORD."

"In hope of eternal life, which God, that cannot lie, promised before the world began;"

"Then she arose with her daughters in law, that she might return from the country of Moab: for she had heard in the country of Moab how that the LORD had visited his people in giving them bread."

"Now we, brethren, as Isaac was, are the children of promise."
