Philippians 1:9

May abound (perisseuh). Present active subjunctive of perisseuw, may keep on overflowing, a perpetual flood of love, "yet more and more" (eti mallon kai mallon), but with necessary limitations (river banks), "in knowledge" (en epignwsei, in full knowledge) "and all discernment" (pash aisqhsei). The delicate spiritual perception (aisqhsi, old word from aisqanomai, only here in N.T. as the verb only in Luke 9:45 in N.T.) can be cultivated as in aisqhthrion ( Hebrews 5:14 )
