with him will I speak mouth to mouth - immediately, not by an interpreter, nor by visionary symbols presented to his fancy.
apparently - plainly and surely.
not in dark speeches - parables or similitudes.
the similitude of the Lord shall he behold - not the face or essence of God, who is invisible (Exo 33:20; Col 1:15; Joh 1:18); but some unmistakable evidence of His glorious presence (Exo 33:2; Exo 34:5). The latter clause should have been conjoined with the preceding one, thus: “not in dark speeches, and in a figure shall he behold the Lord.” The slight change in the punctuation removes all appearance of contradiction to Deu 4:15.
