Targum Jonathan on Exodus
But if a man come maliciously upon his neighbour to kill him with craft, though the priests are ministering at My altar, thence thou shalt take him, and slay him with the sword.
Targum Jerusalem
But if a man deviseth against his neighbour to kill him by guile, though the high priest were standing to minister before Me, from thence thou shalt bring him, and put him to death.
