Ezekiel 3:8; Ezekiel 3:9; Ezekiel 9:4

8 Behold, I have made thy face strong against their faces, and thy forehead strong against their foreheads.

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.

4 And the LORD said unto him, Go through the midst of the city, through the midst of Jerusalem, and set a mark upon the foreheads of the men that sigh and that cry for all the abominations that be done in the midst thereof.
