Commentaries:
Adam Clarke
The roof of thy mouth like the best wine - The voice or conversation of the spouse is most probably what is meant.
Causing the lips of those that are asleep to speak - As good wine has a tendency to cause the most backward to speak fluently when taken in moderation; so a sight of thee, and hearing the charms of thy conversation, is sufficient to excite the most taciturn to speak, and even to become eloquent in thy praises.
