The first section of verses I chose is Isaiah 7:14-16. One thing I noticed here, was in the Old Testament, Immanuel is spelled this way but in the New Testament it is spelled, Emmanuel. Emmanuel means "God with us."
Isaiah 7:14-16 NKJV
14 Therefore the Lord Himself will give you a sign: Behold, the virgin shall conceive and bear a Son, and shall call His name Immanuel.
15 Curds and honey He shall eat, that he may know to refuse the evil and choose the good.
16 For before the Child shall know to refuse the evil and choose the good, the land that you dread will be forsaken by both her kings
For verse 14, I also found Matthew 1:22-23
22Now all this was done that it might be fulfilled which was spoken by the Lord through the prophet, saying:
23"Behold, a virgin shall be with child, and bear a Son, and they shall call His name Immanuel," which is translated, "God with us."
Also for verse 14, Isaiah 9:6-7
6For unto us a Child is born,
Unto us a Son is given;
And the government will be upon His shoulder.
And His name will be called
Wonderful, Counselor, Mighty God,
Everlasting Father, Prince of Peace.
7Of the increase of His government and peace
There will be no end.
Upon the throne of David and over His kingdom,
To order it and establish it with judgment and justice
From that time forward, even forever.
The zeal of the LORD of hosts will perform this.
For Isaiah 7:16, I found Isaiah 8:4
4For before the child shall have knowledge to cry "My father" and "My mother," the riches of Damascus and the spoil of Samaria will be taken away before the king of Assyria.
O come, O come, Emmanuel
O come, O come, Emmanuel,
and ransom captive Israel,
that mourns in lonely exile here
until the Son of God appear.
Emmanuel shall come to thee, O Israel.
O come, thou Rod of Jesse, free
thine own from Satan's tyranny;
from depths of hell thy people save,
and give them victory over the grave.
O come, thou Dayspring, come and cheer
our spirits by thine advent here;
disperse the gloomy clouds of night,
and death's dark shadows put to flight.
O come, thou Key of David, come,
and open wide our heavenly home;
make safe the way that leads on high,
and close the path to misery.
