עַל־פִּ֣י יְהוָ֗ה יִסְעוּ֙ בְּנֵ֣י יִשְׂרָאֵ֔ל וְעַל־פִּ֥י יְהוָ֖ה יַחֲנ֑וּ כָּל־יְמֵ֗י אֲשֶׁ֨ר יִשְׁכֹּ֧ן הֶעָנָ֛ן עַל־הַמִּשְׁכָּ֖ן יַחֲנֽוּ׃
C’est sur l’ordre du Seigneur que partaient les enfants d’Israël, sur l’ordre du Seigneur qu’ils s’arrêtaient: tant que la nuée restait fixée sur le tabernacle, ils demeuraient campés.
Mekhilta DeRabbi Yishmael
(Exodus 15:22) "And Moses made Israel journey from the Red Sea": R. Yehoshua said: This journey was by word of Moses, and all of the others, by word of the L–rd, as it is written (Numbers 9:18) "By word of the L–rd they journeyed and by word of the L–rd they encamped." But this journey was by word of Moses, viz.: "And Moses made Israel journey."
Midrash Tanchuma Buber
R. Eleazar of Modim says: They did journey by divine command, as we find to be so {in one place <or> two or three} [elsewhere in two or three places] (e.g., in Numb. 9:18, 20, 23): AT THE COMMAND OF THE LORD THEY (i.e., the children of Israel) JOURNEYED. So also here (in Exod. 15:22), although he has written THEN [MOSES] HAD <ISRAEL> JOURNEY, they journeyed by divine command. Then what is the meaning of (Exod 15:22:) THEN MOSES HAD <ISRAEL> JOURNEY? When he told them to journey, they did not say to him: Where are we journeying? Into the desert? Perhaps there is nothing there. Rather they arose and journeyed in trustfulness. Jeremiah has said (in Jer. 2:2): GO AND PROCLAIM IN THE EARS OF JERUSALEM, [SAYING: THUS SAYS THE LORD: I HAVE REMEMBERED IN YOUR FAVOR THE FAITHFULNESS OF YOUR YOUTH…, HOW YOU WENT AFTER ME IN THE DESERT, IN A LAND NOT SOWN].
