“On that night could not the king sleep, and he commanded to bring the book of records of the chronicles; and they were read before the king.”
King James Version (KJV)
Matthew Henry's Concise Commentary
6:1-3 The providence of God rules over the smallest concerns of men. Not a sparrow falls to the ground without him. Trace the steps which Providence took towards the advancement of Mordecai. The king could not sleep when Providence had a design to serve, in keeping him awake. We read of no illness that broke his sleep, but God, whose gift sleep is, withheld it from him. He who commanded a hundred and twenty-seven provinces, could not command one hour's sleep.
“He that giveth unto the poor shall not lack: but he that hideth his eyes shall have many a curse.”
