Ezekiel 3:8-10

3:8 Behold, I have made thy face strong against their faces, and thy forehead strong against their foreheads. 3:9 As an adamant harder than flint have I made thy forehead: fear them not, neither be dismayed at their looks, though they [be] a rebellious house. 3:10 Moreover he said unto me, Son of man, all my words that I shall speak unto thee receive in thine heart, and hear with thine ears.
