Wherewith thine enemies have reproached, O Lord - Have reproached thee and me. Wherewith they reproach thy character and cause, and reproach me for having trusted to promises which seem not to be fulfilled. As the representative of thy cause, I am compelled to bear all this, and it breaks my heart.
Wherewith they have reproached the footsteps of thine anointed - Of myself, as the anointed king. They have reproached my footsteps; that is, they have followed me with reproaches - treading along behind me. Wherever I go, wherever I put my foot down in my wanderings, I meet this reproach.
