Sforno on Genesis 44:30/ספורנו על בראשית מ״ד:ל׳

1ועתה כבואי....והורידו עבדיך, after he had warned us, if anything were to happen to him it would no longer be considered an accident but we would be given the blame having been warned not to take him along. A similar consideration is mentioned in Isaiah 48,5 under the heading of בטרם תבא השמעתיך פן תאמר עצבי עשם, “therefore I told you long beforehand, announced things before they happened, that you might not say: “my idol caused them.”
