Who perversely in his heart plots trouble and evil continually;
Who spreads discord and strife.

A false witness who breathes out lies [even half-truths],
And one who spreads discord (rumors) among brothers.

They slice off [in discord] what is on the right hand but are still hungry,
And they eat what is on the left hand but they are not satisfied;
Each eats the flesh of his own arm.

Let no one deceive himself. If anyone among you thinks that he is wise in this age, let him become a fool [discarding his worldly pretensions and acknowledging his lack of wisdom], so that he may become [truly] wise.

so that there would be no division or discord in the body [that is, lack of adaptation of the parts to each other], but that the parts may have the same concern for one another.

that, regarding your previous way of life, you put off your old self [completely discard your former nature], which is being corrupted through deceitful desires,

What leads to [the unending] quarrels and conflicts among you? Do they not come from your [hedonistic] desires that wage war in your [bodily] members [fighting for control over you]?
