Midrash sa Zacarias 10:11: Mekhilta DeRabbi Yishmael, Midrash Tanchuma Buber, Midrash Tanchuma & Bamidbar Rabbah

R. Yehudah b. Ilai says: Idolatry crossed the sea with Israel and Moses removed (it) at that time, viz." "And Moses 'removed' from Israel of the Red Sea" — from the "thing" that was with Israel in (their crossing of) the Red Sea. Which was that? Idolatry, viz. (Zechariah 10:11) "And tzarah (a "rival," i.e., idolatry) passed through the red Sea." Thus, "And Moses 'removed' from Israel … of the Red Sea."

R. Acha says: The Holy One Blessed be He said: If not for your outcry, I would have destroyed them for the idolatry in their midst, viz. (Zechariah 10:11) "And tzarah crossed the sea," tzarah (here) being idolatry, as in (Isaiah 28:20) "and the molten image, tzarah, etc." and as in (Leviticus 18:18) "And a woman to her sister do not take litzror" (to be a rival). And because of your outcry I have withdrawn My wrath, as it is written (Psalms 106:22-23) ("… awesome deeds at the Red Sea) and he thought to destroy them if Moses His chosen one had not stood in the breach before Him, to turn His wrath from destruction."

(Numb. 14:27:) HOW LONG SHALL THIS EVIL CONGREGATION BE MURMURING AGAINST ME? <I HAVE HEARD THE MURMURINGS OF THE CHILDREN OF ISRAEL>….. Let our master instruct us: When a baby has a stone in his hand on the Sabbath, is it permissible to pick him up on the Sabbath?¹⁹Numb. R. 16:26. Thus have our masters taught (in Shab. 21:1): A PERSON MAY PICK UP ONE'S CHILD, EVEN WITH A STONE IN HIS HAND, OR A BASKET (of fruit), EVEN WITH A STONE INSIDE IT. You have learned from the generation of the wilderness that the Holy One, as it were, carried them up in the wilderness. (Deut. 1:31:) AND IN THE WILDERNESS, WHERE YOU SAW HOW THE LORD YOUR GOD CARRIED YOU AS {THE PERSON} [ONE] CARRIES HIS CHILD. Yet there was an object of idolatry in their hand.²⁰Corresponding to the stone in the hand of the child. Thus it is stated (in Neh. 9:18): EVEN THOUGH THEY HAD MADE THEMSELVES A MOLTEN CALF…. And so you find that, when they crossed in the sea, Micah's image (of Jud. 17:3–4) crossed with them, as stated (in Zech. 10:11): AND A RIVAL WIFE²¹Tsarah. The Midrash understands the word in this sense, although most translations follow the other meaning of tsarah, i.e., “affliction,” “distress,” or the like. So also below, Deut. 4:14. SHALL CROSS IN THE SEA.²²Mekhilta deRabbi Ishmael, Pisha 14 on Exod. 12:41; Sanh. 103b; M. Pss. 101:2; Exod. R. 41:1; also Mekhilta deRabbi Ishmael, Wayassa‘ 1 on Exod. 15:22; ySuk. 4:3 (54c); see ARN, A, 34. Still with all this, the Holy One did not forsake them. He said to Moses: I have done a lot of good things with them; yet they are provoking me a lot. I parted the sea for them; they provoked me, as stated (in Pss. 106:7): THEY REBELLED AT THE SEA, [AT THE] REED [SEA]. I led them in the desert, but they provoked me there. And so it says (in Numb. 14:22): THEY HAVE TRIED ME THESE TEN TIMES AND NOT HEARKENED TO MY VOICE. Here also I told you to send them to explore the land, but they provoked me and brought a bad name upon it (i.e., upon the land). I am not able to endure. How long shall I endure them? Where is it shown? From what they read on the matter (in Numb. 14:27): HOW LONG SHALL THIS EVIL CONGREGATION <BE MURMURING AGAINST ME>?
