Devarim 21:7

ידינו לא שפכה [AND THEY SHALL ANSWER AND SAY,] OUR HANDS HAVE NOT SHED [THIS BLOOD] — But would it enter anyone’s mind that the elders of the court are suspect of blood-shedding?! But the meaning of the declaration is: We never saw him and knowingly let him depart without food or escort (if we had seen him we would not have let him depart without these) (Sifrei Devarim 210:2; Sotah 45b). The priests thereupon say (next verse): כפר לעמך ישראל FORGIVE UNTO THY PEOPLE ISRAEL.

וְעָנ֖וּ וְאָמְר֑וּ יָדֵ֗ינוּ לֹ֤א (שפכה) [שָֽׁפְכוּ֙] אֶת־הַדָּ֣ם הַזֶּ֔ה וְעֵינֵ֖ינוּ לֹ֥א רָאֽוּ׃

and they shall answer and say, Our hands have not shed this blood, nor have our eyes seen it.
