Son of Man, Son of Adam, Son of Mankind, or Like man/ Adam: Hebrew, “Ben Adam.” This term is used in a variety of ways throughout the scriptures. In the Book of Ezekiel son of Adam (or son of mankind) is used to address Ezekiel, or to show that mankind is lower than YHVH Elohim and the angels (4 Moses 53:36).
In the Book of Daniel and the Revelation of John (Daniel 7:13-14, Revelation 1:13, 14:14) it is a name for Jesus Christ, coming to signal the end of time and the beginning of the judgement of God. This idea of the Son of Man being Jesus Christ appears in the plates of brass as well with Satan pretending to be holy in 1 Moses 1:22, and Abram seeing Jesus in 1 Moses 26:20.
