Thy lips, O my spouse, drop as the honeycomb: honey and milk are under thy tongue; and the smell of thy garments is like the smell of Lebanon. Thy lips - drop as the honey-comb - Thy words are as delicious to my heart as the first droppings of the honey-comb are to the palate.
Honey and milk are under thy tongue - Eloquence and persuasive speech were compared among the ancients to honey and milk.
Thus Homer, Iliad, lib. i., ver. 247: -
Τοισι δε Νεστωρ
Ηδυεπης ανορουσε, λιγυς Πυλιων αγορητης.
Του και απο γλωσσης μελιτος γλυκιων ῥεεν αυδη.
Experienced Nestor, in persuasion skill'd,
Words sweet as honey from his lips distill'd.
But the figure is common to all writers and languages. A similar expression will be seen in the Gitagovinda.
