9 I have made your forehead harder than flint—like diamond! Do not fear them or be terrified of the looks they give you, for they are a rebellious house.”
Darby
9 As an adamant harder than flint have I made thy forehead. Fear them not, neither be dismayed at them, for they are a rebellious house.
KJV
