Why don't Mormons sing the second verse of, "Hark! The Herald Angels Sing"?

We were singing Christmas Carols tonight and noticed that in the Mormon Hymn book , the following verse has been omitted from, "Hark! The Herald Angels Sing": > Christ, by highest heav'n adored:
Christ, the everlasting > Lord;
Late in time behold him come,
Offspring of the favored > one.
Veil'd in flesh, the Godhead see;
Hail, th'incarnate > Deity:
Pleased, as man, with men to dwell,
Jesus, our > Emmanuel!
