1 Samuel 26:10
Ver. 10. And David said furthermore,.... In order to make Abishai easy, and prevent his doing what he proposed:
[as] the Lord liveth; which was the form of an oath, made to assure Abishai of the truth of what follows, and therefore he need not be hasty to put Saul to death, since it would not be long before he should die, in one or other of the three following ways: either
the Lord shall smite him; suddenly, which the Jews call cutting off, or death by the hand of heaven, by the immediate hand of God:
or his day shall come to die; the time appointed for him to die a natural death, of some disease common to men:
or he shall descend into battle, and perish; which was commonly reckoned death, casual or accidental, and in which last way Saul did die, 1Sa 31:3.
