E un angelo del Signore parlò a Elia il Tishbita: «Alzati, sali incontro ai messaggeri del re di Samaria e di' loro: È forse perché non c'è Dio in Israele che voi andate a consultare Baal-Zebub, dio di Ekron?
Rabbeinu Bahya
וישובו ויחנו פי החירות, “they turned around and encamped at Pi Hachirot. G’d ordered the Israelites to turn around facing Egypt at Pithom renamed Pi Hachirot, seeing that this was the place where they had become free (from slave labour) according to Rashi. The Torah added the words “in front of Baal Tzefon,” as a further means of identification because that idol had survived destruction. All of these details were important to help Pharaoh persuade himself that the Israelites were worth pursuing. When the Torah reports that G’d said to Moses: “I will strengthen the heart of Pharaoh so that he will pursue them” (verse 4), He referred to three causes which would determine Pharaoh’s course of action. 1) Their non-stop day and night travel which would persuade Pharaoh that they were in fact escaping, not following his instructions. 2) Their turnabout convinced Pharaoh that the people were completely lost in the desert. 3) that they should make camp near Baal Tzefon which would give Pharaoh the impression that this deity had impeded the Israelites’ ability to journey forward. The term ”בעל something or other,“ is usually associated with a deity such as בעל זבוב, אלוהי עקרן, בעל פעור, and others. G’d allowed this deity to survive in order to mislead Pharaoh. This is an illustration of Job 12,23: “He causes nations to deceive themselves resulting in their destruction.” The additional words (verse 3) נכחו תחנו על הים, ”opposite it you are to make camp,” was to give Pharaoh the impression that this deity had used the desert to encircle the Israelites, to make them prisoner. This verse contains an allusion to what the Israelites would observe later at the sea.

In the study house. [Targum Yonoson rendered,] in the study6שנה[=study] house. There is a gate in the Temple courtyard, named "the Gate of Chuldoh" [as stated] in Maseches Midos.71:3; according to that Mishnah the two Gates of Chuldoh led to the Temple Mount. Others interpret "במשנה" as "outside the wall/' [i.e.,] between the two walls, which are double8משנה [=double] as in “a double portion [=משנה] of food” in Shemos 16:22. [around] the city. (במשנה [i.e.,] she was teaching the Oral Law to the elders of the generation, i.e., the Mishnah. An annotation of Rabbi Akiva.) In the study house. (From, "These are the words,"9Devarim1:1. until "before the eyes of all Yisroel,"10Ibid. 33-12. 11She expounded on Chumash Devarim which is known as Mishnah Torah [=משנה תורה] because many topics from other Chumashim are repeated in it. i.e., the Book of Devarim, also known as Misheh Torah, and likewise all the things that are repeated in the Torah, she expounded on in public, and she revealed the punishments and the exiles which were doubled for those who transgress the secrets and the allusions of the Torah. The Secret of Righteousness.)
Ramban
NOW THE PRIEST OF MIDIAN HAD SEVEN DAUGHTERS. Scripture does not mention him by name for he is not known [to the reader], but rather epithetically mentions that he was the honored one in his priesthood. This was Jethro, for after he became related to Moses it is written, And Moses went and returned to Jether his father-in-law,93Further, 4:18. and there it is written, And Jethro said to Moses: Go in peace.93Further, 4:18. [This proves that Jether and Jethro are the same person], just as Eliyah and Eliyahu,94Eliyah (II Kings 1:3), Eliyahu (I Kings 17:1). Yirmiyah and Yirmiyahu.95Yirmiyah (Jeremiah 27:1), Yirmiyahu (ibid., 1:1). After he became a proselyte to Judaism, he was called Hobab, as it is written, from the children of Hobab the father-in-law of Moses,96Judges 4:11. for it is the way of all who become converts to Judaism that they be called another name in Israel. And he [Jethro or Hobab] was the son of Reuel, for it is written, And Moses said unto Hobab, the son of Reuel the Midianite.97Numbers 10:29. The verse here stating, And they came to Reuel their father,98Verse 18. means “their father’s father,” just as [Jacob had said], O G-d of my father Abraham,99Genesis 32:10. [and Abraham was his father’s father], and [when speaking of Belshazzar, king of Babylon, Scripture says], Nebuchadnezzar his father,100Daniel 5:2. [while he was his father’s father].101Evil-merodach, king of Babylon, ruled after Nebuchadnezzar (see II Kings 25:27), and he was followed by Belshazzar (see Megillah 11a). Nebuchadnezzar was thus Belshazzar’s grandfather, and yet Scripture (Daniel 5:2) speaks of him as his father. Similarly: Know ye Laban the son of Nahor?102Genesis 29:5. But Laban was really the son of Bethuel, for he was the brother of Rebekah (ibid., 24:29), and of Rebekah it is written that her father was Bethuel (ibid., Verse 15). Bethuel’s father was Nahor (ibid., 22:20-22). Yet Jacob asked, Know ye Laban the son of Nahor? It is because a grandfather is called “father.” And Mephibosheth the son of Saul.103II Samuel 19:25. Mephibosheth was the son of Jonathan (ibid., 4:4), who was the son of Saul. There are many other such verses.
[Jethro’s daughters came and told Reuel their grandfather of how Moses came to their aid — as is related in Verses 18-19 — and did not tell Jethro] because the priest was not found in the house since he was preoccupied with the ministry in his temple, and so they came to the grandfather. It is possible that the verse, And Moses was content to dwell with the man,104Verse 21. refers to the priest mentioned above [in Verse 16 — namely, Jethro]105The intent of Ramban’s words is as follows: According to the above-mentioned interpretation that Jethro was not to be found in his home and that consequently his daughters told Reuel, his father, what had happened (as stated in Verses 18-20), it should follow that the expression, And Moses was content to dwell with ‘the man’ (Verse 21) refers to Reuel, and it was Reuel who gave Moses Zipporah his granddaughter as a wife. But, continues Ramban, it is possible that “the man” in Verse 21 refers back to “the priest” in Verse 16, and so it was Jethro who gave Moses his daughter in marriage. — for it was he who gave Moses Zipporah his daughter.
