Genesis 37:21

Reuben heard it - Though Reuben appears to have been a transgressor of no ordinary magnitude, if we take Genesis 35:22 according to the letter, yet his bosom was not the habitation of cruelly. He determined, if possible, to save his brother from death, and deliver him safely to his father, with whose fondness for him he was sufficiently acquainted. Josephus, in his usual way, puts a long flourishing speech in the mouth of Reuben on the occasion, spoken in order to dissuade his brethren from their barbarous purpose; but as it is totally unfounded, it is worthy of no regard.

37:21 And Reuben heard it — God can raise up friends for his people, even among their enemies. Reuben of all the brothers had most reason to be jealous of Joseph, for he was the first-born, and so entitled to those distinguishing favours which Jacob was conferring on Joseph, yet he proves his best friend. Reuben's temper seems to have been soft and effeminate, which had betrayed him to the sin of uncleanness, while the temper of the two next brothers, Simeon and Levi, was fierce, which betrayed them to the sin of murder, a sin which Reuben startled at the thought of. He made a proposal which they thought would effectually destroy Joseph, and yet which he designed should answer his intention of rescuing Joseph out of their hands, probably hoping thereby to recover his father's favour which he had lately lost; but God over-ruled all to serve his own purpose of making Joseph an instrument to save much people alive. Joseph was here a type of Christ. 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; he came from heaven to earth to seek and save us; yet then malicious plots were laid against him; he came to his own, and his own not only received him not, but consulted, This is the heir, come let us kill him. This he submitted to, in pursuance of his design to save us.
