'Brow' in the Bible

But the children of Israel will not give ear to you; for they have no mind to give ear to me: for all the children of Israel have a hard brow and a stiff heart.

See, I have made your face hard against their faces, and your brow hard against their brows.

Like a diamond harder than rock I have made your brow: have no fear of them and do not be overcome by their looks, for they are an uncontrolled people.
