פּירוש אויף שמות 2:21

ויואל — Translate this as the Targum does: AND HE WAS WILLING. Similar are: (Judges 19:6) “Be content (הואל), I pray thee, and tarry all night”; (Joshua 7:7) “would that we had been content (הואלנו)”; (Genesis 18:31) “I am content (הואלתי) to speak”. A Midrashic explanation is that it has the sense of taking an oath (אלה), so that it should be rendered, “And Moses pledged himself by an oath to remain with the man” — he swore to him that he would not stir from Midian save by his permission (cf. Exodus 4:18) (Nedarim 65a).

Moshe agreed to reside, etc. and he gave his daughter, Tzipporah, to Moshe: And at first glance, the word, "to Moshe," is extra; and it should have said, "and he gave him, Tzipporah, his daughter." Indeed, when Scripture says that he gave his daughter, Tzipporah, to Moshe, it is saying that this was like Moshe's intention of taking this this one from all of his daughters. For she had appeared individually to him. And it also seems that it can be said that even Yitro knew that Tzipporah was fit for Moshe, since he was a great sage. That is why it said, "And he gave." Meaning that he gave Tzipporah, because he knew she was his [proper] mate. And hence he gave his daughter, Tzipporah, to Moshe; meaning she was the one fitting for the level of Moshe. For she was the most proper of women, 'maidens see and acclaim her, etc.'

ויתן את צפורה בתו למשה, “He gave his daughter Tzipporah to Moses (as a wife.)” What is the significance of the name “Tzipporah?” She had run towards Moses like a bird (צפור) An alternate interpretation: she was beautiful as the morning at the time of sunrise. She lit up the atmosphere in the morning. The Aramaic word צפרא means: “morning;” it is used to describe how welcome the morning is. Our author quotes Ezekiel 7,7 “the day is near,” as well as Judges 7,3: as a bird flies from Mount Gilad,” to support his point.
