His mischief shall return upon his own head, and his violent dealing shall come down upon his own crown.
All Commentaries on Psalms 7:16 Go To Psalms 7
Augustine of Hippo
AD 430
18. "His toil shall be turned on his head, and his iniquity shall descend on his pate" (ver. 16). For he had no mind to escape sin: but was brought under sin as a slave, so to say, as the Lord saith, "Whosoever sinneth is a slave." His iniquity then will be upon him, when he is subject to his iniquity; for he could not say to the Lord, what the innocent and upright say, "My glory, and the lifter up of my head." He then will be in such wise below, as that his iniquity may be above, and descend on him; for that it weigheth him down and burdens him, and suffers him not to fly back to the rest of the saints. This occurs, when in an ill regulated man reason is a slave, and lust hath dominion.
