וַיֹּ֤אמֶר אֵלָיו֙ דָּוִ֔ד דמיך [דָּמְךָ֖] עַל־רֹאשֶׁ֑ךָ כִּ֣י פִ֗יךָ עָנָ֤ה בְךָ֙ לֵאמֹ֔ר אָנֹכִ֥י מֹתַ֖תִּי אֶת־מְשִׁ֥יחַ יְהוָֽה׃ (ס)
Rashi on II Samuel
Your blood is on your own head. The responsibility for your death rests on your own head.13This is Targum Yonasan’s translation. There is no one to punish for your death but yourself.
