Genesis 37:4

And when his brethren saw that their father loved him more than all his brethren,.... Which they perceived by various things in his behaviour to him, by his words, his looks, his gestures, and particularly by the coat he had made him, which distinguished him from the rest:

they hated him, and could not speak peaceably unto him; they not only inwardly hated him, but they could not conceal their hatred, but betrayed it by their speech unto him; they could not speak to him on any occasion, but in a cross, surly, ill natured manner; they could not salute him, or give him the common salutation, Peace be to thee, as Aben Ezra suggests.
