And the roof of thy mouth like the best wine for my beloved, that goeth down sweetly, causing the lips of those that are asleep to speak.
Roof of thy mouth - thy voice (Proverbs 15:23).
Best wine - the new wine of the Gospel kingdom (Mark 14:25), poured out at Pentecost.
For my beloved - (Song of Solomon 4:10.) Here first the daughters call him theirs, and become one with the bride. The steps successively are - Song of Solomon 1:5, where they misjudge her; Song of Solomon 3:11 where they are called to go forth and behold King Solomon with the crown of His espousals (which are going on now, and will go on until the bride espoused shall become the wife (Revelation 21:9); Song of Solomon 5:8, where the possibility of their finding Him, before she regained Him, is expressed; Song of Solomon 5:9 where they are so struck with her love to the Beloved that they ask after Him; Song of Solomon 6:1, where they wish to 'seek Him with her;' Song of Solomon 7:6; Song of Solomon 7:9, where they break forth into admiration of her, and finally make her Beloved their Beloved.
Causing ... asleep to speak - (Isaiah 35:6; Ephesians 5:14.) Jesus Christ's first miracle turned water into 'good wine kept until now,' just as the Gospel revives those asleep and dying under the law (Romans 7:1-25; Romans 8:1).
