신명기 17:4 미드라쉬: Sifrei Devarim

"And you shall inquire": of the Torah. "and you shall search out": from the witnesses. "and you shall ask": of the Talmud. Here (in respect to a man's serving idolatry) it is written (Ibid. 17:4) "And it be told to you, and you hear, and you inquire well," and elsewhere (in respect to scheming witnesses) (19:18) "And the judges inquire well" — "well" - "well" for an identity (gezeirah shavah.) (We are hereby taught) that he (the witness) undergoes seven cross-examinations (chakiroth).

(Devarim 17:4) "And it be told to you, and you hear, and you search it out well": And elsewhere (Ibid. 13:15) it is written "And you shall inquire, and you shall search out, and you shall ask well," and elsewhere (Ibid. 19:18) "And the judges shall inquire well." "well" - "well," for a gezeirah shavah (identity). We are hereby taught that he is examined with seven chakiroth (cross-examinations). This tells me only of chakiroth. Whence do I derive (the same for) bedikoth (examinations)? From (13:15, 17:4) "and, behold, true and correct is the thing."

(Devarim 19:18) "And the judges shall inquire well. And elsewhere, (Ibid. 13:15) "And you shall inquire, and you shall search out, and you shall ask well," and elsewhere (Ibid. 17:4) "And it be told to you, and you hear, and you shall search it out well" — "well" - "well," for an identity (gezeirah shavah ). We are hereby taught that he is subject to seven inquiries (chakiroth, cross-examinations). Whence is it derived that there are also bedikoth ("examinations," factual review)? From (Ibid.) "and, behold, true and correct is the thing." Whence is it derived (that through his testimony) he is branded as "false"? From (Ibid. 19:18) "and, behold, a false witness is the witness."
