TSK · Genesis 21:1

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

Remember me, O Jehovah, with the favor that thou bearest unto thy people; Oh visit me with thy salvation,

Blessed [be] the Lord, the God of Israel; For he hath visited and wrought redemption for his people,

(as it is written, A father of many nations have I made thee) before him whom he believed, [even] God, who giveth life to the dead, and calleth the things that are not, as though they were.

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