Exodus 18:1

וישמע יתרו AND JETHRO HEARD — What was the particular report which he heard so that he came? — The division of the Red Sea and the war with Amalek (cf. (Mekhilta; Zevachim 116a). יתרו JETHRO — He was called by seven names: Reuel, Jether, Jethro, Hobab, Heber, Keni and Putiel. He was called Jether (from יִתֵּר “to add”) because he added (it was through him that there was added) a section to the Torah; viz., that beginning at (21 ff.) “Moreover thou shalt provide”. Jethro — so was he called because when he became a proselyte and fulfilled the divine precepts one more letter was added to his name (יתר). Hobab — because he loved (חִבֵּב) the Torah (cf. Mekhilta). — Hobab is certainly identical with Jethro, as it is said, (Judges 4:11) “of the sons of Hobab, the father-in-law of Moses” and therefore it is correct to say that Hobab is one of his names. But as to Reuel there are some who say that he is not identical with Jethro, but that he was Hobab’s (Jethro’s) father, as may be seen from Numbers 10:29. Then what, according to this view, would be the meaning of (Exodus 2:18) “And they came to Reuel, their father” (from which it would appear that Reuel and Jethro are the same)? It means their grandfather, for children call their grandfather: father. This is to be found in Sifrei Bamidbar 78 (on Numbers 10:29). חתן משה MOSES’ FATHER-IN-LAW — Here Jethro prided himself on his relationship to Moses: I, the father-in-law of the king. Previously, however, Moses had made whatever greatness he had hinge upon his relationship to his father-in-law, the chieftain of Midian, as it is said, (Exodus 4:18) “And he returned to Jethro, his father-in-law” (Mekhilta). למשה ולישראל TO MOSES AND TO ISRAEL — Moses alone is of equal in importance to all Israel (Mekhilta). את כל אשר עשה ALL THAT [GOD] HAD DONE for them through the falling of the Manna and through the well (cf. Rashi on Numbers 21:17) and by the defeat of Amalek. כי הוציא ה׳ וגו׳ THAT THE LORD HAD BROUGHT FORTH etc. — this was greater than all other things, and is therefore singled out for mention (cf. Mekhilta).

וַיִּשְׁמַ֞ע יִתְר֨וֹ כֹהֵ֤ן מִדְיָן֙ חֹתֵ֣ן מֹשֶׁ֔ה אֵת֩ כׇּל־אֲשֶׁ֨ר עָשָׂ֤ה אֱלֹהִים֙ לְמֹשֶׁ֔ה וּלְיִשְׂרָאֵ֖ל עַמּ֑וֹ כִּֽי־הוֹצִ֧יא יְהֹוָ֛ה אֶת־יִשְׂרָאֵ֖ל מִמִּצְרָֽיִם׃

When Yitro, the priest of Midyan, Moshe’s father in law, heard of all that God had done for Moshe, and for Yisra᾽el his people, and that the Lord had brought Yisra᾽el out of Miżrayim;
