The Hebrew phrase "ben adam" means "human being" . The phrase "son of man" is retained as a form of address here and throughout Ezekiel because of its possible association with “Son of Man” in the New Testament.
As he spoke, the Spirit came into me and raised me to my feet, and I heard him speaking to me.
And you, son of man, do not be afraid of them or their words. Do not be afraid, though briers and thorns are all around you and you live among scorpions. Do not be afraid of what they say or be terrified by them, though they are a rebellious people.
