Midrash su Salmi 94:8

"How great are thy works, O Lord!" (Ps. 92:5). Adam began to glorify and to praise the Name of the Most High, as it is said, "How great are thy works, O Lord!" (ibid.) but Thy thoughts are very deep, like the great deep exceedingly (deep), as it is said, "Thy thoughts are very deep" (ibid.). "A brutish man knoweth not" (Ps. 92:6). Every man of Israel who is brutish (in knowledge) and has not learnt understanding, let the wise men of Israel teach him the ways of the Torah, as it is said, "Consider, ye brutish among the people" (Ps. 94:8). But a man who is an expert among the nations of the world is still foolish. Why? For he knoweth not the words of the Torah, as it is said, "Neither doth a fool || understand this" (Ps. 92:6).
