Deuteronomy 21:9
JPS-1917וְאַתָּ֗ה תְּבַעֵ֛ר הַדָּ֥ם הַנָּקִ֖י מִקִּרְבֶּ֑ךָ כִּֽי־תַעֲשֶׂ֥ה הַיָּשָׁ֖ר בְּעֵינֵ֥י יְהֹוָֽה׃ {ס}
So shalt thou put away the innocent blood from the midst of thee, when thou shalt do that which is right in the eyes of the LORD.
Rashi Commentary
ואתה תבער BUT THOU SHALT PUT AWAY [THE GUILT OF INNOCENT BLOOD FROM AMONG YOU] — This teaches that if the murderer is found after the heifer’s neck was broken he must nevertheless be put to death, — and this is what Scripture describes as הישר בעיני ה׳ RIGHT IN THE EYES OF THE LORD (cf. Sotah 47b; Ketubot 37b and Tosafot on Ketubot 37b:16.1 ואח"כ נמצא ההורג).
