G4910–συνευωχέομαι–suneuōcheomai

receiving the wages of unrighteousness; people who count it pleasure to revel in the day-time, spots and blemishes, reveling in their deceit while they feast with you;

συνευωχούμενοι suneuōchoumenoi “feasting with”

These are hidden rocky reefs in your love feasts when they feast with you, shepherds who without fear feed themselves; clouds without water, carried along by winds; autumn leaves without fruit, twice dead, plucked up by the roots;

συνευωχούμενοι, suneuōchoumenoi “feasting together [with you]”
