Reference for Shevuot 49:6

כיצד אמר שבועה שאתן לאיש פלוני ושלא אתן שנתתי ושלא נתתי

T SHALL SLEEP,' OR, I shall not SLEEP.' This cannot be, for R. Johanan said: He who says, I shall not sleep three days,' is given stripes, and he may sleep immediately. - There, he said 'three'; here, he did not say 'three'. <br>
