Isaiah 8:18

And he lifted up his eyes and saw the women and the children and said, “Who are these with you?” And he said, “The children whom God has graciously given your servant.”

“And they shall become a sign and a wonder on you and your seed forever.

I have become a marvel to many, For You are my strong refuge.

And Yahweh said, “Even as My servant Isaiah has gone naked and barefoot three years as a sign and wonder against Egypt and Ethiopia,

‘This will be the sign to you,’ declares Yahweh, ‘that I am going to punish you in this place, so that you may know that My words will surely be established against you for evil.’

“Now as for you, get yourself an iron plate and set it up as an iron wall between you and the city, and establish your face toward it so that it is under siege, and besiege it. This is a sign to the house of Israel.

“In their sight, carry the baggage on your shoulder and bring it out in the dark. You shall cover your face so that you cannot see the land, for I have set you as a wondrous sign to the house of Israel.”

‘Now listen, Joshua the high priest, you and your friends who are sitting in front of you—indeed they are men who are a wondrous sign, for behold, I am going to bring in My servant the Branch.

And again, “I will put My trust in Him.” And again, “Behold, I and the children whom God has given Me.”
