'Slayer' in the Bible

then you shall select for yourselves cities to be cities of refuge, so that the one who kills any person unintentionally may escape there.

then the congregation shall judge between the offender and the blood avenger according to these ordinances.

But if at any time the one guilty of manslaughter comes outside the border of his city of refuge to which he fled,

“Now this is the case of the offender (manslayer) who may escape there and live [protected from vengeance]: when he kills his neighbor unintentionally, not having hated him previously—

otherwise the avenger of blood might pursue the offender in the heat of anger, and overtake him, because it is a long way, and take his life, even though he did not deserve to die, since he did not hate his neighbor beforehand.

so that the person (manslayer) who kills any person unintentionally, without premeditation, may flee there, and they shall be your refuge from the blood avenger.

If the blood avenger pursues him, they shall not hand the offender (manslayer) over to him, because he killed his neighbor unintentionally and without premeditation and did not hate him beforehand.

He shall live in that city until he has stood before the congregation for judgment [and if acquitted of murder he must stay there], until the death of the one who is the high priest in those days. Then the offender (manslayer) shall return to his own city and his own house from which he fled.’”

The sword [of Babylon] is ready to be polished so that it may be handled and put to use; the sword is sharpened and polished to be put in the hand of the slayer (Nebuchadnezzar).

Ephraim, as I have seen,Is planted in a pleasant [and prosperous] meadow like Tyre;But Ephraim will bring out his children to the executioner [for slaughter].
