Psalms 91:9

His eyes are upon the ways of man, and he seeth all his goings. There is no darkness, nor shadow of death, where the workers of iniquity may hide themselves.—Can any hide himself in secret places that I shall not see him? . . . Do not I fill heaven and earth? saith the Lord .

Thou shalt not be afraid for the terror by night; . . . nor for the pestilence that walketh in darkness . . . Because thou hast made the Lord , which is my refuge, even the Most High, thy habitation; there shall no evil befall thee, neither shall any plague come nigh thy dwelling.—He that keepeth thee will not slumber. The Lord is thy keeper: the Lord is thy shade upon thy right hand. The sun shall not smite thee by day, nor the moon by night. The Lord shall preserve thee from all evil.

Jacob awaked out of his sleep, and he said, Surely the Lord is in this place; and I knew it not. And he was afraid and said, How dreadful is this place! this is none other but the house of God, and this is the gate of heaven.

The eyes of the Lord run to and fro throughout the whole earth, to shew himself strong in the behalf of them whose heart is perfect toward him.

The Israelites in the wilderness were continually exposed to change.

Whenever the pillar stayed its motion, the tents were pitched; but tomorrow, ere the morning sun had risen, the trumpet sounded, the ark was in motion, and the fiery, cloudy pillar was leading the way through the narrow defiles of the mountain, up the hillside, or along the arid waste of the wilderness.
