His mouth is most sweet: yea, he is altogether lovely. This is my beloved, and this is my friend, O daughters of Jerusalem.
His mouth is most sweet - literally, 'His palate is sweetnesses; yea, all over lovelinesses;' i:e., He is the essence of these qualities. "Mouth;" so Song of Solomon 1:2: not the same as "lips" (Song of Solomon 5:13); His breath (Isaiah 11:4). "All over" - all the beauties scattered among creatures are transcendently concentrated in Him (Colossians 1:19).
My beloved - for I love Him.
My friend - for He loves me (Proverbs 18:24). Holy boasting, (Psalms 34:2; 1 Corinthians 1:31.)
