'Sleepest' in the Bible

Awake, why sleepest thou, O Lord? arise, cast us not off for ever.

When thou goest, it shall lead thee; when thou sleepest, it shall keep thee; and when thou awakest, it shall talk with thee.

And he cometh, and findeth them sleeping, and saith unto Peter, Simon, sleepest thou? couldest not thou watch one hour?

Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light.
