There are two principal points in this narrative,--the sad insight that it gives into the state of the household in which so much of the world's history and hopes was wrapped up, and the preludings of Joseph's future in his dreams. As to the former, the account of it is introduced by the statement that Joseph, at seventeen years of age, was set to work, according to the wholesome Eastern usage, and so was thrown into the company of the sons of the two slave-women, Bilhah and Zilpah. Delitzsch understands 'lad' in verse 2 in the sense in which we use 'boy,' as meaning an attendant. Joseph was, then, told off to be subordinate to these two sets of his rough brothers. The relationship was enough to rouse hatred in such coarse souls. And, indeed, the history of Jacob's household strikingly illustrates the miserable evils of polygamy, which makes families within the family, and turns brothers into enemies. Bilhah's and Zilpah's sons reflected in their hatred of Rachel's their mothers' envy of the true wife of Jacob's heart. The sons of the bondwoman were sure to hate the sons of the free. If Joseph had been like his brothers, they would have forgiven him his mother. But he was horrified at his first glimpse of unrestrained young passions, and, in the excitement of disgust and surprise, 'told their evil report.' No doubt, his brothers had been unwilling enough to be embarrassed by his presence, for there is nothing that wild young men dislike more than the constraint put on them by the presence of an innocent youth; and when they found out that this 'milk-sop' of a brother was a spy and a telltale, their wrath blazed up. So Joseph had early experience of the shock which meets all young men who have been brought up in godly households when they come into contact with sin in fellow-clerks, servants, students, or the like. It is a sharp test of what a young man is made of, to come forth from the shelter of a father's care and a mother's love, and to be forced into witnessing and hearing such things as go on wherever a number of young men are thrown together. Be not 'partaker of other men's sins.' And the trial is doubly great when the tempters are elder brothers, and the only way to escape their unkindness is to do as they do. Joseph had an early experience of the need of resistance; and, as long as the world is a world, love to God will mean hatred from its worst elements. If we are 'sons of the day,' we cannot but rebuke the darkness.
