'Slumber' in the Bible

There is none weary, nor stumbling in it, It doth not slumber, nor sleep, Nor opened hath been the girdle of its loins, Nor drawn away the latchet of its sandals.

Blind are his watchmen -- all of them, They have not known, All of them are dumb dogs, they are not able to bark, Dozing, lying down, loving to slumber.
