Isaiah 40 : 25-31
To whom, then, will you liken Me or make Me equal? says the Holy One. Lift up your eyes and see : who has created all this? He has ordered them as a starry host and called them each by name. So mighty is His power, so great His strength, that not one of them is missing.
How can you say, o Jacob, how can you complain, o Israel, that your destiny is hidden from Me, that your rights are ignored by YHVH? Have you not known, have you not heard that YHVH is an everlasting God, the Creator of the ends of the earth? He does not grow tired or weary, His knowledge is without limit.
He gives strength to the enfeebled, He gives vigour to the wearied. Youth may grow tired and faint, young men will stumble and fall, but those who hope in YHVH will renew their strength. They will soar as with eagle’s wings; they will run and not grow weary; they will walk and never tire.

Isaiah 7 : 10-14 and Isaiah 8 : 10c
Once again YHVH addressed Ahaz, “Ask for a sign from YHVH your God, let it come either from the deepest depths or from the heights of heaven.” But Ahaz answered, “I will not ask, I will not put YHVH to the test.”
Then Isaiah said, “Now listen, descendants of David. Have you not been satisfied trying the patience of people, that you also try the patience of my God? Therefore the Lord Himself will give you a sign : The Virgin is with Child and bears a Son and calls His Name Immanuel, for God-is-with-us.”
