Adam Clarke on Psalms 73:6

Pride compasseth them about as a chain - Perhaps there is an allusion here to the office which some of them bore. Chains of gold, and golden rings, were ensigns of magistracy and civil power. As these chains encompassed their necks, or the rings their wrists and fingers, as the signs of the offices in virtue of which they acted; so חמס chamas, violence, oppressive conduct, encompassed them. They made no other use of their great power, than to oppress the poor and the needy; and to drive things to extremities. The Chaldee, instead of a chain, represents this as a crown or diadem, which they had formed out of the plunder of the poor and defenseless.
