KJV:
I sleep, but my heart waketh: it is the voice of my beloved that knocketh, saying, Open to me, my sister, my love, my dove, my undefiled: for my head is filled with dew, and my locks with the drops of the night.
NASB:
"I was asleep but my heart was awake. A voice! My beloved was knocking: 'Open to me, my sister, my darling, My dove, my perfect one! For my head is drenched with dew, My locks with the damp of the night.'
