Charles Ellicott Commentary Psalms 73:6

"Therefore pride is as a chain about their neck; Violence covereth them as a garment." — Psalms 73:6 (ASV)

Therefore. —Better,

“Therefore pride is their necklace,
And violence their mantle.”

The first metaphor might have been suggested either by the fact that the rich lavished large sums on jewellery, especially necklaces (see Note, Song of Solomon 1:10), or possibly from the usual description of the proud as “stiffnecked.”
