Exodus 4:20

על החמור UPON “THE” ASS — the ass designated for this purpose: this was the ass which Abraham had saddled for the purpose of travelling to bind Isaac on Mount Moriah, and this, too, is the ass upon which King Messiah will once show himself in public, as it is said, (Zechariah 9:9) “[Behold, thy king cometh unto thee, …] lowly and riding upon an ass” (Pirkei DeRabbi Eliezer 31). וישב ארצה מצרים ויקח משה את מטה AND HE RETURNED TO THE LAND OF EGYPT: AND MOSES TOOK THE STAFF [OF GOD] — “Earlier and later” are not strictly observed in the Scriptures (i. e. incidents are not necessarily related in the exact order in which they occur. Here it should state: He took the staff etc. and returned to Egypt; cf. v. 17).

וַיִּקַּ֨ח מֹשֶׁ֜ה אֶת־אִשְׁתּ֣וֹ וְאֶת־בָּנָ֗יו וַיַּרְכִּבֵם֙ עַֽל־הַחֲמֹ֔ר וַיָּ֖שׇׁב אַ֣רְצָה מִצְרָ֑יִם וַיִּקַּ֥ח מֹשֶׁ֛ה אֶת־מַטֵּ֥ה הָאֱלֹהִ֖ים בְּיָדֽוֹ׃

And Moshe took his wife and his sons, and set them upon an ass, and he returned to the land of Miżrayim: and Moshe took the rod of God in his hand.
