Son of man (1.) Denotes mankind generally, with special reference to their weakness and frailty (Job 25:6; Psalms 8:4; Psalms 1:144; Psalms 1:146; Isaiah 51:12, etc.).
(2.) It is a title frequently given to the prophet Ezekiel, probably to remind him of his human weakness.
(3.) 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 Psalms 80:17 and Daniel 7:13 with this application. It denotes the true humanity of our Lord. He had a true body (Hebrews 2:14; Luke 24:39) and a rational soul. He was perfect man.
