Testament of Dan 2

¹And now, my children, behold I am dying, and I tell you of a truth, that unless ye keep yourselves from the spirit of lying and of anger, and love truth and longsuffering, ye shall perish. ²For anger is blindness, and does not suffer one to see the face of any man with truth. ³For though it be a father or a mother, he behaveth towards them as enemies; though it be a brother, he knoweth him not; though it be a prophet of the Lord, he disobeyeth him; though a righteous man, he regardeth him not; though a friend, he doth not acknowledge him. ⁴For the spirit of anger encompasseth him with the net of deceit, and blindeth his eyes, and through lying darkeneth his mind, and giveth him its own peculiar vision. ⁵And wherewith encompasseth it his eyes? With hatred of heart, so as to be envious of his brother.
