וְלָ֤מָּה תְכַבְּדוּ֙ אֶת־לְבַבְכֶ֔ם כַּאֲשֶׁ֧ר כִּבְּד֛וּ מִצְרַ֥יִם וּפַרְעֹ֖ה אֶת־לִבָּ֑ם הֲלוֹא֙ כַּאֲשֶׁ֣ר הִתְעַלֵּ֣ל בָּהֶ֔ם וַֽיְשַׁלְּח֖וּם וַיֵּלֵֽכוּ׃
Wherefore then do ye harden your hearts, as the Egyptians and Pharaoh hardened their hearts? when He had wrought among them, did they not let the people go, and they departed?
Exodus
And so that you may relate in the ears of your son and grandson how I made a mockery of the Egyptians, and the miraculous signs I performed among them. You will then know that I am Adonoy.”
