He did not see in the Egyptian that he would say them. “He looked this way and that.” The “This way” is him seeing whether there were good deeds in him, and the “And that” is that he looked whether a righteous son would come out of him. Promptly, “He saw there was no one,” meaning he saw in the spirit of holiness that a righteous son would not emerge from him.
