Genesis 50:15

We have here the settling of a good correspondence between Joseph and his brethren, now that their father was dead. Joseph was at court, in the royal city; his brethren were in Goshen, remote in the country; yet the keeping up of a good understanding, and a good affection, between them, would be both his honour and their interest. Note, When Providence has removed the parents by death, the best methods ought to be taken, not only for the preventing of quarrels among the children (which often happen about the dividing of the estate), but for the preserving of acquaintance and love, that unity may continue even when that centre of unity is taken away. I. Joseph's brethren humbly make their court to him for his favour. 1. They began to be jealous of Joseph, not that he had given them any cause to be so, but the consciousness of guilt, and of their own inability in such a case to forgive and forget, made them suspicious of the sincerity and constancy of Joseph's favour (Gen 50:15): Joseph will peradventure hate us. While their father lived, they thought themselves safe under his shadow; but now that he was dead they feared the worst from Joseph. Note, A guilty conscience exposes men to continual frights, even where no fear is, and makes them suspicious of every body, as Cain, Gen 4:14. Those that would be fearless must keep themselves guiltless.

When Joseph's brethren saw that their father was dead, they said, Joseph will peradventure hate us, &c.--Joseph was deeply affected by this communication. He gave them the strongest assurances of his forgiveness and thereby gave both a beautiful trait of his own pious character, as well as appeared an eminent type of the Saviour.
