'Coucheth' in the Bible

If thou doest well, shall it not be lifted up? and if thou doest not well, sin coucheth at the door: and unto thee shall be its desire, but do thou rule over it.

Even by the God of thy father, who shall help thee, And by the Almighty, who shall bless thee, With blessings of heaven above, Blessings of the deep that coucheth beneath, Blessings of the breasts, and of the womb.
