Deuteronomy 11:2

וִֽידַעְתֶּם֮ הַיּוֹם֒ כִּ֣י׀ לֹ֣א אֶת־בְּנֵיכֶ֗ם אֲשֶׁ֤ר לֹֽא־יָדְעוּ֙ וַאֲשֶׁ֣ר לֹא־רָא֔וּ אֶת־מוּסַ֖ר יְהוָ֣ה אֱלֹהֵיכֶ֑ם אֶת־גָּדְל֕וֹ אֶת־יָדוֹ֙ הַחֲזָקָ֔ה וּזְרֹע֖וֹ הַנְּטוּיָֽה׃

καὶ καὶ γνώσεσθε σήμερον ὅτι οὐχὶ τὰ παιδία ὑμῶν, ὅσοι οὐκ οἴδασιν οὐδὲ ἴδοσαν τὴν παιδίαν κυρίου τοῦ θεοῦ σου καὶ τὰ μεγαλεῖα αὐτοῦ καὶ τὴν χεῖρα τὴν κραταιὰν καὶ τὸν βραχίονα τὸν ὑψηλόν,

Y comprended hoy: porque no hablo con vuestros hijos que no han sabido ni visto el castigo de Jehová vuestro Dios, su grandeza, su mano fuerte, y su brazo extendido,

Know this day that it is not your children who have known and seen the discipline of the LORD your God: His greatness, His mighty hand, and His outstretched arm;
