Testament of Dan 3
Dan teaches his sons that anger is not merely a mood but a governing spirit — one that colonizes the body, blinds the soul's own judgment, and supplies the angry man with force beyond his natural measure. The strong man with wrath has threefold destructive power; even the weak man doubles his capacity for harm. The chapter identifies this spirit as the right-hand companion of Satan, paired always with lying, so that cruelty and deception operate together as a unified agency against the soul and against others.
1
My children, mischievous is anger, for it becometh as a soul to the soul itself; and the body of the angry man it maketh its own, and over his soul it getteth the mastery, and it bestoweth upon the body its own power, that it may work all iniquity; and whenever the soul doeth aught, it justifieth what has been done, since it seeth not. Therefore he who is wrathful, if he be a mighty man, hath a treble might in his anger; one by the might and aid of his servants, and a second by his wrath, whereby he persuadeth and overcometh in injustice: and having a third of the nature of his own body, and of his own self working the evil. And though the wrathful man be weak, yet hath he a might twofold of that which is by nature; for wrath ever aideth such in mischief. This spirit goeth always with lying at the right hand of Satan, that his works may be wrought with cruelty and lying.
