Ezekiel 3:8

This may be to remove the objection of the prophet, who might plead the softness of his own metal, and pretend shameless sinners will scoff a young prophet out of countenance. Behold, says God, consider. I have made; given. They have given themselves this impudent countenance; I have given thee true courage, constancy, and manly carriage. Thy forehead strong; the same answer in words very little varying. God will qualify and gift him for this work among this people, and edge his own tools to cut into the hardest metal. So Isaiah 1:7 Jeremiah 1:18 Micah 3:8.
