"Son of a human being" or "Son of humanity." God calls Ezekiel this to emphasize that Ezekiel is only a human being. God is eternal and powerful, but humans are not. See how you translated this in [Ezekiel 2:1](../02/01.md). Alternate translation: "Mortal person" or "Human"
This exclamation expresses the fear that people would feel about a certain day when terrible and frightening things will happen. Alternate translation: "Oh that day" or "Oh, what a frightening day is coming" (See: [[rc://en/ta/man/jit/figs-exclamations]])
