'Slumbering' in the Bible

“In a dream, a vision of the night [one may hear God’s voice],When deep sleep falls on menWhile slumbering upon the bed,

Your shepherds are sleeping, O king of Assyria! Your officers are slumbering! Your people are scattered like sheep on the mountains and there is no one to regather them!

But beware of slumbering; and every moment pray that you may be fully strengthened to escape from all these coming evils, and to take your stand in the presence of the Son of Man."

Thirsting for riches, they will trade on you with their canting talk. From of old their judgement has been working itself out, and their destruction has not been slumbering.
