לֹא־יָב֣וּזוּ לַ֭גַּנָּב כִּ֣י יִגְנ֑וֹב לְמַלֵּ֥א נַ֝פְשׁ֗וֹ כִּ֣י יִרְעָֽב׃
מע קען ניט פֿאַראַכטן דעם גנבֿ אַז ער גנבֿעט, אָנצופֿילן זײַן לײַב װען ער איז הונגעריק.
Mishneh Torah, Prayer and the Priestly Blessing
A priest who is free from any of these disqualifications, even though he is not a scholar nor punctilious in the observance of religious duties, and even though people talk about him and his dealings are not marked by strict integrity, nevertheless pronounces the Priestly Benediction and should not be prevented from performing the rite; since it is a duty incumbent on every qualified priest to bless the people, and we do not say to a wicked man, "Be still more wicked and abstain from fulfilling religious duties."
