John Wesley on Numbers 12:8

Mouth to mouth - That is, distinctly, by an articulate voice; immediately, not by an interpreter, nor by shadows and representations in his fancy, as it is in visions and dreams; and familiarly. Apparently - Plainly and certainly. Dark speeches - Not in parables, similitudes, dark resemblances; as by shewing a boiling pot, an almond tree, &c. to Jeremiah, a chariot with wheels, &c. to Ezekiel. The similitude - Not the face or essence of God, which no man can see and live, Exo 33:20, but some singular manifestation of his glorious presence, as Exo 33:11,20. Yea the Son of God appeared to him in an human shape, which he took up for a time, that he might give him a foretaste of his future incarnation. My servant - Who is so in such an eminent and extraordinary manner.
