Murdering with Guile

To which murderer is the Torah referring when it states “you shall take him from My altar to die”? Chazal’s interpretation included only one who murders intentionally with premeditation, as opposed to one who murders accidentally. The verses, however, include a third type of murderer who is a composite of the first two types. He murders intentionally, but pretends to have done so unknowingly. It is concerning this murderer that the Torah commands that he be removed from the place of his refuge, from the 'altar,' and put to death. Examples exist throughout the biblical text, from Cain who murders Hevel, through Yoav ben Tzeruya’s murder of Avner, Amasa and Uriya, to Yishmael ben Netanya who murders Gedaliya ben Achikam.
