The headword phrase comes from Psalm 72.27 LXX, quoted more fully at pi 2079.
The verb e)cwlo/qreusas is second person singular aorist of e)coloqreu/w, better spelled e)coleqreu/w, from o)/leqros. The participle poreu/onta is an emendation from the editio princeps for the manuscript reading porneu/onta (also found in the LXX). The comment seems mistaken, since the verb poreu/omai uses middle forms.
