'Waketh' in the Bible

{A Song of degrees for Solomon.} Except the LORD build the house, they labour in vain that build it: except the LORD keep the city, the watchman waketh but in vain.

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.
