Genesis 45:24

Fall not out. Literally, “be not moved,” or “be not disturbed,” that is, with violent emotion, particularly anger. This is generally understood as an admonition against quarreling, particularly over their relative responsibility for the course events had taken. This advice gives evidence of Joseph’s deep insight into human nature. He had already overheard Reuben denounce his brothers severely (ch. 42:22). He might well suppose that Reuben and others would repeat these things, even more vehemently, when alone.

Reuben might have argued how different the result would have been had they taken his advice. After that each would have added his own comments, and a serious quarrel might have been the result. The unexpected prosperity into which they had fallen might also serve to arouse old feelings of enmity, particularly with respect to Benjamin. All this was now restrained by Joseph’s sober and timely advice.
