Isaiah 48 : 17-19

Thus says YHVH, your Redeemer, the Holy One of Israel : I, YHVH, your God, teach you what is best for you; I lead you in the way that you must go. Had you paid attention to My commandments, your peace would have been like a river, your righteousness like the waves of the sea.

Your descendants would have been like the sand, and those born of your stock like its grains, their names never cut off nor blotted out from My presence.

Isaiah 7 : 10-14 and Isaiah 8 : 10

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.”

“Devise a plan and it will be thwarted, make a resolve and it will not stand, for God-is-with-us.”
