Midrasz do Ozeasza 4:1

If so, what is the intent of "And you shall learn them and you shall heed them to do them"? Scripture hereby apprises us that doing (the mitzvah) is contingent upon learning, and not, learning up doing. And thus do we find that the punishment for (not) learning is greater than that of (not) doing, viz.: (Hoshea 4:1) "Hear the word of the L-rd, O children of Israel. For the L-rd has a quarrel with the dwellers of the land. For there is no truth, and there is no lovingkindness, and there is no knowledge of the L-rd in the land."
