to die: for a living thing to lose its life and stop living.
This is the plain, ordinary word for dying. It covers every kind of death the Bible reports: old age at the end of a long life, sudden death by violence or accident, death from plague or famine, and the death sentence God warns will follow disobedience. The word itself does not say how a person died or whether the death was deserved; it simply states that life ended.
Because it is the basic word, it carries the weight of some of the Bible's heaviest moments. It is the word in the first warning to the man and woman, "you will surely die," and the word that closes the long lists of the early generations, "and he died." When the subject is a person who has already died, the same word in its naming form means "a dead person" or "a corpse."
A few of its uses press past simple biology. To be near death, to feel as good as dead from fear or grief, or to face a death the law has decreed are all carried by this one word. What ties them together is not the cause but the outcome: the end of life.
