Exodus 10:2 Midrash

וּלְמַ֡עַן תְּסַפֵּר֩ בְּאָזְנֵ֨י בִנְךָ֜ וּבֶן־בִּנְךָ֗ אֵ֣ת אֲשֶׁ֤ר הִתְעַלַּ֙לְתִּי֙ בְּמִצְרַ֔יִם וְאֶת־אֹתֹתַ֖י אֲשֶׁר־שַׂ֣מְתִּי בָ֑ם וִֽידַעְתֶּ֖ם כִּי־אֲנִ֥י יְהוָֽה׃

and that thou mayest tell in the ears of thy son, and of thy son’s son, what I have wrought upon Egypt, and My signs which I have done among them; that ye may know that I am the LORD.’
