Emmanuel
Isaiah 7:14
Therefore the Lord himself will give you a sign: The virgin will be with child and will give birth to a son, and will call him Emmanuel.
Matthew 1:21-23
21 She will give birth to a son, and you are to give him the name Jesus, because he will save his people from their sins.”
22 All this took place to fulfill what the Lord had said through the prophet:
23 “The virgin will be with child and will give birth to a son, and they will call him Immanuel”—which means, “God with us.”
Sanctify
Isaiah 8:12-13
12 “Do not call conspiracy everything that these people call conspiracy; do not fear what they fear, and do not dread it.
13 The LORD Almighty is the one you are to regard as holy, he is the one you are to fear, he is the one you are to dread,
1 Peter 3:15
But in your hearts set apart Christ as Lord. Always be prepared to give an answer to everyone who asks you to give the reason for the hope that you have. But do this with gentleness and respect,
Stumbling
Isaiah 8:14
And he will be a sanctuary; but for both houses of Israel he will be a stone that causes men to stumble and a rock that makes them fall. And for the people of Jerusalem he will be a trap and a snare.
Romans 9:32-33
32 Why not? Because they pursued it not by faith but as if it were by works. They stumbled over the “stumbling stone.”
33 As it is written: “See, I lay in Zion a stone that causes men to stumble and a rock that makes them fall, and the one who trusts in him will never be put to shame.”
Children
Isaiah 8:17-18
17 I will wait for the LORD, who is hiding his face from the house of Jacob. I will put my trust in him.
18 Here am I, and the children the LORD has given me. We are signs and symbols in Israel from the LORD Almighty, who dwells on Mount Zion.
Hebrews 2:13
And again, “I will put my trust in him.” And again he says, “Here am I, and the children God has given me.”
