Genesis 37:5 - Ellicott's Commentary On The Whole Bible

Joseph dreamed a dream. — Though dreams as a rule do but arise from the mind being wearied with overmuch business (Ecclesiastes 5:3), or other trivial causes; yet as being from time to time used by God for providential purposes, they are occasionally described as a lower kind of prophecy (Numbers 12:6-8; Deuteronomy 13:1; 1 Samuel 28:15). In the life of Joseph they form the turning point in his history, and it is to be noticed that while revelations were frequently made to Jacob, we have henceforward no record of any such direct communication from God to man until the time of Moses. The utmost granted to Joseph was to dream dreams; and after this the children of Israel in Egypt were left entirely to natural laws and influences. (Comp. Note on Genesis 26:2.)
