וְלֹֽא־נָתַן֩ יְהוָ֨ה לָכֶ֥ם לֵב֙ לָדַ֔עַת וְעֵינַ֥יִם לִרְא֖וֹת וְאָזְנַ֣יִם לִשְׁמֹ֑עַ עַ֖ד הַיּ֥וֹם הַזֶּֽה׃
곧 그 큰 시험과 이적과 큰 기사를 네가 목도하였느니라
Rashi on Deuteronomy
ולא נתן ה' לכם לב לדעת YET THE LORD HATH NOT GIVEN YOU A HEART TO KNOW — i.e. to understand the loving-kindnesses of the Omnipresent and to cleave unto Him.
Sforno on Deuteronomy
ולא נתן ה' לכם לב לדעת, even though He had tried by means of His teachings and His miracles to give the people a knowing heart, as we know from Exodus 10,20ולמען תספר.....וידעתם כי אני ה', “and in order that you will tell…and be aware that I am the Lord,” the lesson had not taken hold due to your overwhelming quarrelsomeness.
Rashbam on Deuteronomy
עד היום הזה, even though you have witnessed all His great deeds.
