וַיִּרְא֣וּ אֶחָ֗יו כִּֽי־אֹת֞וֹ אָהַ֤ב אֲבִיהֶם֙ מִכָּל־אֶחָ֔יו וַֽיִּשְׂנְא֖וּ אֹת֑וֹ וְלֹ֥א יָכְל֖וּ דַּבְּר֥וֹ לְשָׁלֹֽם׃
And when his brethren saw that their father loved him more than all his brethren, they hated him, and could not speak peaceably unto him.
Targum Jonathan on Genesis
And his brothers saw that their father loved him more than all his brethren, and they cherished enmity against him, and were unwilling to speak peacefully with him.
