Commentator John Gill notes that the phrase 'if you take this one also' implies Jacob suspected his other sons were involved in Joseph's disappearance. The plea that losing Benjamin would 'bring my gray hairs with sorrow to the grave' is not hyperbole; it expresses a genuine, life-threatening grief that would overwhelm the elderly patriarch.
