Veni, Veni Emanuel was a series of Latin antiphons made by an unknown author and translated by John M. Neale. The song is based upon various prophecies in the Bible and the title is from Isaiah 7:14
Therefore the Lord himself will give you a sign. Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel.
