Song of Solomon 4:11

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<-144 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.
