'Hardened' in the Bible

-- And it hath passed over into it, hardened and hungry, And it hath come to pass, That it is hungry, and hath been wroth, And made light of its king, and of its God, And hath looked upwards.

Fled away hath Madmenah, The inhabitants of the high places have hardened themselves.

O LORD, why hast thou made us to err from thy ways, and hardened our heart from thy fear? Return for thy servants' sake, the tribes of thine inheritance.
