'Sleep' in the Bible

On this I awakened, and saw; and my sleep was sweet to me.

When they are heated, I will make their feast, and I will make them drunken, that they may rejoice, and sleep a perpetual sleep, and not wake, says Yahweh.

I will make drunk her princes and her wise men, her governors and her deputies, and her mighty men; and they shall sleep a perpetual sleep, and not wake up, says the King, whose name is Yahweh of Armies.
