Another explanation: As she purified the entire house of her father like the blood of a bird (tzipor, used in purifying some impurities). Rabbi Yose bar Chaninah said, 'They sought to mistreat them, as it is written (Deuteronomy 22:27), 'the engaged girl cried for help, but there was no one to save her.'" (Since the same word is used for Moshe saving them here.) "He surely drew (dalah dalo) for us" - in this world and in the world to come. He drew once and gave the whole flock to drink. "He said to his daughters, 'And where is he'" - maybe he is from that seed of, "where is Sarah, your wife," through whom the whole world is blessed. And why was he called the priest (kohen) of Midian? Because the sons of his daughters would in the future be high priests. Rabbi Yehoshua says, "It was [priesthood to] idolatry, like the matter about which it is said (Judges 18:30), 'and Yehonatan the son of Gershom the son of Menashe.'" R. Elazar the Modaai says, "He was a minister, like the matter about which it is stated (II Samuel 8:18), 'and the sons of David were ministers (kohanim).'" Rabbi Yochanan said in the name of Rabbi Yose ben Kisma, "Great is a drink, as it distanced two families away from Israel, as it is stated (Deuteronomy 23:5). 'Because of the matter that they did not greet you with bread and water.'" But Rabbi Yochanan himself said, "It distances the close, etc., and it brings the distant close, as it is stated (Exodus 2:20), 'call him and let him eat bread'; it brings the Divine Presence to the prophets of Baal, as it is stated (I Kings 13:20), 'While they were sitting at the table'; and it causes the eye to avoid the wicked, [as in] Yonatan ben Gershom." Rabbi Simon said in the name of Rabbi Eliezer, "He is the one that did kindness to Moshe, as it is written, 'Why did you abandon the man? Call him and let him eat bread.'" Rabbi Simon said, "There is no kindness here, he paid him his wage, as it is written, 'He surely drew for us.'" And when did the Holy One, blessed be He, pay him back? In the days of Shaul, as it is written (I Samuel 15:6), "Shaul said to the Kenites (Yitro's descendants), 'Come, withdraw, etc.'" And did he do kindness to all of the Children of Israel; and did he not do kindness to Moshe alone? Rather it is to teach you that anyone who does kindness to one of the Children of Israel, Scripture counts it as if he did kindness to all of the Jewish people. And behold these things are a fortiori (kal vechomer): With one who does kindness for someone who he is obligated to, see what the Holy One, blessed be He, paid him back; all the more so is it with someone who does kindness for someone who he is not obligated to.
