Son of man
Denotes mankind generally, with special reference to their weakness and frailty (Job 25:6; Ps. 8:4; 144:3; 146:3; Isa. 51:12, etc.).
It is a title frequently given to the prophet Ezekiel, probably to remind him of his human weakness.
In the New Testament it is used forty-three times as a distinctive title of the Saviour. In the Old Testament it is used only in Ps. 80:17 and Dan. 7:13 with this application. It denotes the true humanity of our Lord. He had a true body (Heb. 2:14; Luke 24:39) and a rational soul. He was perfect man.
