Emmael is a Christian term, which means God is with us.
Emmanuel comes from Matthew 1:23 in the Bible: "Behold, a virgin will conceive and give birth to a son, and they will call his name Immanuel."
Christianity believes that before Jesus was born, God told Joseph in a dream that Mary would give birth to a son, and people would call him Immanuel, which means God is with us.
This name came about more than 700 years ago when the prophet Isaiah predicted that a son born of a virgin would be called Immanuel, and he would be the savior that the Jews were looking forward to. Christianity believes that the name Immanuel explains the purpose and method of Jesus' birth into the world.
Extended information
The source background of Immanuel:
The name given by the prophet Isaiah to a child in the time of King Ahaz (Isaiah Joshua 7:14). The prophecy was fulfilled for a short time in Ahaz's life, for the child was still a doll when Ahaz's enemies were defeated.
The child to whom Isaiah refers was most likely the unborn son of Ahaz, Hezekiah, who later became one of the greatest kings of all Judea.
Hezekiah’s mother was a virgin when Isaiah prophesied, but Hezekiah was not born of a virgin. He can be called "Immanuel" because he believed in God more than any other Jewish king before or after him, and God showed that he was with Hezekiah when he defeated the Assyrian army (1 Kings 19:35 ).
