Exodus 18:2

And Jethro the father-in-law of Mosheh took Zipporah his wife, whom Mosheh had sent back from him after going into Mizraim,

AFTER HE HAD SENT HER AWAY. Because Scripture had [previously] mentioned, And Moses took his wife and his sons… and he returned to the land of Egypt, it became necessary to state here that she was in her father’s house, as Moses had sent her there. It is possible that Scripture is stating that Jethro took [Zipporah, Moses’s wife], to return her to him although he had sent her away. Having heard all that G-d had done for Moses, he thought that it was now time for her to follow the king wherever he would go.

אחר שלוחיה, seeing that the Torah had never told us that Moses had sent his wife and children back to Midian after they had arrived in Egypt, the Torah had to fill us in on this if we are to understand what is written here. Some commentators believe that what is meant is that now that Moses was in a position to do this he had sent her the gifts a husband normally gives his bride. We find something similar reported of Pharaoh giving his daughter, Solomon’s wife, Gezer Chazor and Megiddo as a dowry. in Kings I 9,15. The former interpretation in the plain meaning of our verse. There would be no point is Yitro bringing Tzipporah back to her husband, when we had never heard that Moses had sent her back to her father in the first place. The last that we had heard was that Tzipporah had accompanied Moses and even circumcised his son (their son) during Moses’ temporary absence. If she had been sent to her father at that time, why did the Torah not report something important like this? The Torah has reported far less important matters more than once, such as Genesis 9,18 וחם הוא אבי כנען, “and Cham, the one who was the father of Canaan.” This information was provided by the Torah in Genesis 10,6 where it belonged. It is therefore not unusual for the Torah to provide some information at a juncture we would not have suspected it.

אחר שלוחיה. The word אחר describes something happening later, as it did in Genesis 22,13 where Avraham only found the ram which had been caught in the thicket by its horns after the binding of Yitzchok was over. Similarly, in Leviticus 15,28 the word אחר תטהר, means that after the procedure described by the Torah previously the woman in question would become ritually clean again. [the point of our author is that in all the examples quoted by him the Bible had informed the reader of the background to the present happening. Why would it not have done so here also? Ed.]

אחר שלוחיה. After she (Tzipporah) had sent a message to him to find out where they were encamped. Moses had informed her that the Israelites would not stop anywhere for any length of time until they would reach the mountain of G’d, Mount Chorev, where they would serve the Lord. She must have known about this as Moses must have told her of G’d’s prediction in Exodus 3,12 that once out of Egypt the Jewish people would serve the Lord there at that mountain. This is the reason why it took Yitro so long before he came as he had to wait until the Jewish people would make camp for longer than one night.
