I will both lay me down in peace, and sleep: for you, LORD, only make me dwell in safety.
I have noticed in the books of travellers, this observation, "We found it exceedingly difficult to obtain a tent keeper who could keep awake at night." One gentleman speaks of discovering a thief in his tent, and when he went outside to call the watchman he found that the man had gone so soundly to sleep that he could only be aroused by one or two gentle kicks. When a man has been travelling with you all day, it is unreasonable to expect him to keep awake through the night to, take care of you. Hence the beauty of the words, "Behold He that keepeth Israel." etc.
( C. H. Spurgeon.).
