'Sleeping' in the Bible

And all the people were weeping and crying for her; but he said, Do not be sad, for she is not dead, but sleeping.

I say to you, In that night there will be two men sleeping in one bed, and one will be taken away and the other let go.

And, getting up from prayer, he came to the disciples, and saw that they were sleeping for sorrow.

And he said, Why are you sleeping? Get up, and give yourselves to prayer, so that you may not be put to the test.
