Exodus 14:6

וְחִזַּקְתִּי אֶת־לֵב־פַּרְעֹה וְרָדַף אַחֲרֵיהֶם וְאִכָּבְדָה בְּפַרְעֹה וּבְכָל־חֵילוֹ וְיָדְעוּ מִצְרַיִם כִּֽי־אֲנִי יְהוָה וַיַּֽעֲשׂוּ־כֵֽן

And I will harden Pharaoh’s heart, and he shall follow after them; and I will get Me honour upon Pharaoh, and upon all his host; and the Egyptians shall know that I am the LORD.’ And they did so.

וַיֻּגַּד לְמֶלֶךְ מִצְרַיִם כִּי בָרַח הָעָם וַיֵּהָפֵךְ לְבַב פַּרְעֹה וַעֲבָדָיו אֶל־הָעָם וַיֹּֽאמרוּ מַה־זֹּאת עָשִׂינוּ כִּֽי־שִׁלַּחְנוּ אֶת־יִשְׂרָאֵל מֵעָבְדֵֽנוּ

And it was told the king of Egypt that the people were fled; and the heart of Pharaoh and of his servants was turned towards the people, and they said: ‘What is this we have done, that we have let Israel go from serving us?

וַיִּקַּח שֵׁשׁ־מֵאוֹת רֶכֶב בָּחוּר וְכֹל רֶכֶב מִצְרָיִם וְשָׁלִשִׁם עַל־כֻּלּֽוֹ

And he took six hundred chosen chariots, and all the chariots of Egypt, and captains over all of them.

וַיְחַזֵּק יְהֹוָה אֶת־לֵב פַּרְעֹה מֶלֶךְ מִצְרַיִם וַיִּרְדֹּף אַחֲרֵי בְּנֵי יִשְׂרָאֵל וּבְנֵי יִשְׂרָאֵל יֹצְאִים בְּיָד רָמָֽה

And the LORD hardened the heart of Pharaoh king of Egypt, and he pursued after the children of Israel; for the children of Israel went out with a high hand.
