there was the cloud with the darkness it cast a spell.. lift your rod hold out your arm over the sea

And you lift up your rod and hold out your arm over the sea and split it, so that the Israelites may march into the sea on dry ground.
The messenger of God, who had been going ahead of the Israelite army, now moved and followed behind them; and the pillar of cloud shifted from in front of them and took up a place behind them,
וַיָּבֹ֞א בֵּ֣ין ׀ מַחֲנֵ֣ה מִצְרַ֗יִם וּבֵין֙ מַחֲנֵ֣ה יִשְׂרָאֵ֔ל וַיְהִ֤י הֶֽעָנָן֙ וְהַחֹ֔שֶׁךְ וַיָּ֖אֶר אֶת־הַלָּ֑יְלָה וְלֹא־קָרַ֥ב זֶ֛ה אֶל־זֶ֖ה כׇּל־הַלָּֽיְלָה׃
and it came between the army of the Egyptians and the army of Israel. Thus there was the cloud with the darkness, and it cast a spell upon the night, so that the one could not come near the other all through the night.
וַיֵּ֨ט מֹשֶׁ֣ה אֶת־יָדוֹ֮ עַל־הַיָּם֒ וַיּ֣וֹלֶךְ יְהֹוָ֣ה ׀ אֶת־הַ֠יָּ֠ם בְּר֨וּחַ קָדִ֤ים עַזָּה֙ כׇּל־הַלַּ֔יְלָה וַיָּ֥שֶׂם אֶת־הַיָּ֖ם לֶחָרָבָ֑ה וַיִּבָּקְע֖וּ הַמָּֽיִם׃
Then Moses held out his arm over the sea and יהוה drove back the sea with a strong east wind all that night, and turned the sea into dry ground. The waters were split,
and the Israelites went into the sea on dry ground, the waters forming a wall for them on their right and on their left.
Is this not the very thing we told you in Egypt, saying, ‘Let us be, and we will serve the Egyptians, for it is better for us to serve the Egyptians than to die in the wilderness’?”
וַיֹּ֨אמֶר מֹשֶׁ֣ה אֶל־הָעָם֮ אַל־תִּירָ֒אוּ֒ הִֽתְיַצְּב֗וּ וּרְאוּ֙ אֶת־יְשׁוּעַ֣ת יְהֹוָ֔ה אֲשֶׁר־יַעֲשֶׂ֥ה לָכֶ֖ם הַיּ֑וֹם כִּ֗י אֲשֶׁ֨ר רְאִיתֶ֤ם אֶת־מִצְרַ֙יִם֙ הַיּ֔וֹם לֹ֥א תֹסִ֛פוּ לִרְאֹתָ֥ם ע֖וֹד עַד־עוֹלָֽם׃
But Moses said to the people, “Have no fear! Stand by, and witness the deliverance which יהוה will work for you today; for the Egyptians whom you see today you will never see again.
יְהֹוָ֖ה יִלָּחֵ֣ם לָכֶ֑ם וְאַתֶּ֖ם תַּחֲרִשֽׁוּן׃ {פ}
יהוה will battle for you; you hold your peace!”

וַיֹּ֤אמֶר יְהֹוָה֙ אֶל־מֹשֶׁ֔ה מַה־תִּצְעַ֖ק אֵלָ֑י דַּבֵּ֥ר אֶל־בְּנֵי־יִשְׂרָאֵ֖ל וְיִסָּֽעוּ׃
Then יהוה said to Moses, “Why do you cry out to Me? Tell the Israelites to go forward.
And you lift up your rod and hold out your arm over the sea and split it, so that the Israelites may march into the sea on dry ground.
And I will stiffen the hearts of the Egyptians so that they go in after them; and I will gain glory through Pharaoh and all his warriors, his chariots, and his riders.
Let the Egyptians know that I am יהוה, when I gain glory through Pharaoh, his chariots, and his riders.”
The messenger of God, who had been going ahead of the Israelite army, now moved and followed behind them; and the pillar of cloud shifted from in front of them and took up a place behind them,
and it came between the army of the Egyptians and the army of Israel. Thus there was the cloud with the darkness, and it cast a spell upon the night, so that the one could not come near the other all through the night.
Then Moses held out his arm over the sea and יהוה drove back the sea with a strong east wind all that night, and turned the sea into dry ground. The waters were split,
and the Israelites went into the sea on dry ground, the waters forming a wall for them on their right and on their left.
The Egyptians came in pursuit after them into the sea, all of Pharaoh’s horses, chariots, and riders.
At the morning watch, יהוה looked down upon the Egyptian army from a pillar of fire and cloud, and threw the Egyptian army into panic.
[God] locked the wheels of their chariots so that they moved forward with difficulty. And the Egyptians said, “Let us flee from the Israelites, for יהוה is fighting for them against Egypt.”

Then יהוה said to Moses, “Hold out your arm over the sea, that the waters may come back upon the Egyptians and upon their chariots and upon their riders.”
Moses held out his arm over the sea, and at daybreak the sea returned to its normal state, and the Egyptians fled at its approach. But יהוה hurled the Egyptians into the sea.
The waters turned back and covered the chariots and the riders—Pharaoh’s entire army that followed them into the sea; not one of them remained.
But the Israelites had marched through the sea on dry ground, the waters forming a wall for them on their right and on their left.
Thus יהוה delivered Israel that day from the Egyptians. Israel saw the Egyptians dead on the shore of the sea.
And when Israel saw the wondrous power which יהוה had wielded against the Egyptians, the people feared יהוה; they had faith in יהוה and in God’s servant Moses.
15
Then Moses and the Israelites sang this song to יהוה. They said:
I will sing to יהוה, for He has triumphed gloriously;
Horse and driver He has hurled into the sea.
יהוה is my strength and might;
He is become my deliverance.
This is my God and I will enshrine Him;
The God of my father’s [house], and I will exalt Him.
יהוה, the Warrior—
יהוה is His name!
Pharaoh’s chariots and his army
He has cast into the sea;
And the pick of his officers
Are drowned in the Sea of Reeds.
