Deuteronomy 30:11

11. Hidden from thee Rather, is not too difficult for thee. Jehovah has not imposed upon his people conditions impossible of fulfilment; nor are his requirements difficult of comprehension. “Nowhere does the fundamental religious thought of prophecy find clearer expression than in Deuteronomy the thought that Jehovah asks nothing for himself, but asks it as a religious duty that man should render to man what is right that his will lies not in any unknown height, but in the moral sphere which is known and understood by all.” J. WELLHAUSEN, in Encyclopaedia Britannica, 9th ed., vol. xiii, pp. 415, 416.

Neither is it far off Comp. Luke 17:21.
