Genesis 37:31

I. Joseph would soon be missed, great enquiry would be made for him, and therefore his brethren have a further design, to make the world believe that Joseph was torn in pieces by a wild beast; and this they did, 1. To clear themselves, that they might not be suspected to have done him any mischief. Note, We have all learned of Adam to cover our transgression, Job 31:33.

Joseph's brethren kept their own and one another's counsel for some time, but their villany came to light at last, and it is here published to the world, and the remembrance of it transmitted to every age. 2.

Love is always apt to fear the worst concerning the person beloved; there is a love that casteth out fear, but that is a perfect love.

How strongly does he represent to himself the direful idea of Joseph's misery! Sleeping or waking, he imagines he sees the wild beast setting upon Joseph, thinks he hears his piteous shrieks when…

37:31-35 The old family propensity for deception seized the brothers’ imagination. Jacob had killed a young goat to deceive Isaac (27:5-17); now Jacob’s sons deceived him with a goat (see study note on 30:34-36).
