And they said one to another, Behold, this dreamer cometh.

King James Translators' Notes

dreamer: Heb. master of dreams

Jamieson-Fausset-Brown Bible Commentary

19. Behold, this dreamer cometh-literally, "master of dreams"-a bitterly ironical sneer. Dreams being considered suggestions from above, to make false pretensions to having received one was detested as a species of blasphemy, and in this light Joseph was regarded by his brethren as an artful pretender. They already began to form a plot for Joseph's assassination, from which he was rescued only by the address of Reuben, who suggested that he should rather be cast into one of the wells, which are, and probably were, completely dried up in summer.

Matthew Henry's Concise Commentary

37:12-22 How readily does Joseph wait his father's orders! Those children who are best beloved by their parents, should be the most ready to obey them. See how deliberate Joseph's brethren were against him. They thought to slay him from malice aforethought, and in cold blood. Whosoever hateth his brother is a murderer, 1Jo 3:15. The sons of Jacob hated their brother because their father loved him. New occasions, as his dreams and the like, drew them on further; but this laid rankling in their hearts, till they resolved on his death. God has all hearts in his hands. Reuben had most reason to be jealous of Joseph, for he was the first-born; yet he proves his best friend. God overruled all to serve his own purpose, of making Joseph an instrument to save much people alive. Joseph was a type of Christ; for though he was the beloved Son of his Father, and hated by a wicked world, yet the Father sent him out of his bosom to visit us in great humility and love. He came from heaven to earth to seek and save us; yet then malicious plots were laid against him. His own not only received him not, but crucified him. This he submitted to, as a part of his design to redeem and save us.
