הַצִּ֘ילֵ֤נִי מִדָּמִ֨ים ׀ אֱֽלֹהִ֗ים אֱלֹהֵ֥י תְּשׁוּעָתִ֑י תְּרַנֵּ֥ן לְ֝שׁוֹנִ֗י צִדְקָתֶֽךָ׃
Deliver me from bloodguiltiness, O God, Thou God of my salvation; so shall my tongue sing aloud of Thy righteousness.
Shemot Rabbah
... one who kills a person/nefesh . . . it is as if he removed the icons of the king, and he is sentenced and has no life, for the human is created in the d’mut of the ministering angels
