בראשית יב:כ פירוש: רש״י, רד״ק, טור הארוך וSiftei Chakhamim

ויצו עליו AND PHARAOH GAVE COMMAND CONCERNING HIM— עליו means for his sake — to escort him and to protect him.

ויצו עליו פרעה אנשים, to protect both him and his wife, so that the Egyptians would not molest them.

וישלחו אותו ואת אשתו ואת כל אשר לו, “they escorted him and his wife and all his belongings.” Even though Avraham had treated them badly they did not take back the gifts they had given to him.”
