Exodus 18:1

What report did he hear and [that brought him to] come? He heard of the splitting of the sea, and the war with Amalek.

This is greater than all [of the other miracles Hashem did].

And Jethro, prince of Midian, the father-in-law of Mosheh, heard all that the Lord had done for Mosheh and for Israel His people, and that the Lord had brought forth Israel from Mizraim.

Our Rabbis have already differed concerning this section.. The difference of opinion is between Rabbi Yehoshua and Rabbi Eleazar of Modi’im, Rabbi Yehoshua maintaining that Jethro arrived before the Giving of the Torah, and Rabbi Eleazar saying that he came after the Torah had been given. Some say that Jethro came to Moses before the Giving of the Torah, as the sequence of the sections of the Torah indicate, and some say that he came after the Giving of the Torah. Now this [latter] opinion [that he came after the Giving of the Torah] is certainly assisted by the verse [here] which states, And Jethro, Moses’ father-in-law, came with his sons and his wife unto Moses into the wilderness where he was encamped, at the mount of G-d. Thus Scripture states that Jethro came to Moses when he was encamped before Mount Sinai, the place in which the Israelites camped for one year, this being the meaning of the expression, where he was encamped. Moreover, Moses said to Jethro, and I make them know the statutes of G-d, and His laws, [thus indicating that the Torah had already been given]. Besides, it says here, And Moses let his father-in-law depart; and he went his way unto his own land., Verse 27. This had taken place in the second year when they journeyed from Mount Sinai, as it is said in the parashah (section) of Beha’alothcha: And Moses said unto Hobab, the son of Reuel the Midianite, Moses’ father-in-law: we are journeying, 10:29. Hobab is identified as Jethro (Rashi). Now if all this happened before the Giving of the Torah, how could Moses say, We are journeying, etc.? There it is written: And he [Hobab] said unto him [Moses]: I will not go; but I will depart to mine own land and to my kindred,, Verse 30. this being identical with the departure mentioned here, and he went his way unto his own land., Verse 27.
They have further brought proof [that Jethro came after the Torah had been given] from that which Scripture says, The Eternal our G-d spoke unto us in Horeb, saying: Ye have dwelt long enough in this mountain; turn you, and take your journey. There it is said, And I spoke unto you at that time, saying: I am not able to bear you myself alone… So I took the heads of your tribes, wise men, etc., Verses 9-15. This is the advice that Jethro [gave Moses on the morning after he arrived at the camp, as mentioned here further on in Verse 13]. …

אשר עשה אלוקים למשה, that Pharaoh never tried to harm him personally, and that G’d provided him with such an imposing image in the eyes of Pharaoh and his servants seeing He let him perform all these miracles.

וישמע יתרו, the word שמיעה for hearing is used when recording or referring to something which did not occur at the time it is being reported. When one hears of something which is just happening, the Torah uses the term ראיה, “seeing,” i.e. first hand knowledge of something. It does not matter whether the sound of the happening comes from a distant location or is nearby within one’s eyesight. Examples of the use of the word ראיה “seeing” being used for matters which were heard second hand, not seen, are found in Genesis 42,1 where Yaakov, resident in the land of Canaan, is reported as “seeing” that there was grain for sale in Egypt. Clearly, the Torah refers to Yaakov having heard about it. Seeing the matter was not near at hand nor had occurred just then, the Torah used the words וירא יעקב, “Jacob saw.” A similar use of the word “seeing,” וירא for something not actually seen is Numbers 22,2 where Bileam is reported as “seeing” all that Israel had done to the Emorite kings. Bileam had not seen any of it, but had heard that the Israelites had defeated the two most powerful Emorite kings Sichon and Og. A third example confirming our theory would be Deuteronomy 28,10 where the people of the globe are reported as expressing their conviction that the Jewish people are G’d’s darlings and that they would therefore be in awe of them. Clearly, the people of the globe could not have “seen” this, but they had heard about the success of the Jewish nation. The events inspiring such feelings among the nations of the globe had occurred over a period of time, not all at once. However, if we understand the words כי הוציא as meaning כאשר הוציא, “when He took out,” we must understand Yitro as saying that he had heard all that G’d had done for Israel at the time when He took them out of Egypt. This would include a reference to all the plagues, the drowning of the Egyptians army, etc. It was this information which had prompted him to journey into the desert himself instead of sending a messenger who would accompany Tzipporah and her children so that they would be reunited with their husband/father. He was primarily motivated by his quest for G’d. This is similar to Chronicles II 32,31 where the king of Babylon wanted to have evidence of the reports he had received about the miraculous recovery from his illness which King Chizkiyah had experienced.

וישמע יתרו, “Yitro heard;” this man had seven different names. They were: Yitro, Yeter, Chever, Chovev, Keyni, Puti-el, and R’uel. According to some scholars, it was Yitro’s father who was called R’-uel. They base themselves on Exodus 2,18: ותבאנה אל רעואל אביהם, “they came to their father, R’uel.” Children are in the habit of referring to their grandfather as their “father.” Still, this raises the following difficulty for those scholars: if they were correct, how do we understand the line in Numbers 10,29: ויאמר משה לחובב בן רעואל המדיני חותן משה, “Moses said to Chovav, son of R’uel, the Midianite, the father-in-law of Moses;” We may have to answer this by saying that the scholar who says that that the scholar who identifies Yitro with R’uel, may not consider that the name “Chovav” was merely a compliment to this man who looked with great fondness at the Torah, חיבב את התורה, as explained by Rashi, but that he must also hold that R’uel was the father of Yitro. The reason why Yitro was also named יתר, Yeter, “addition,” is that on account of this man a whole portion has been added to the Torah in his honour. At any rate, as pointed out by Rashi, we do not have seven names for him. The “names” given in the Mechilta quoted by Rashi are only the adjectives which were added to his original name on account of historical events or events in his personal life, such as his conversion to Judaism. Judges 4,11 as well as the expression: וחבר הקיני נפרד מקין מבני חובב חותן משה, “Chever the Kenite had separated from the other Kenites, descendants of Chovav father-in-law of Moses,” presents another difficulty.
