Genesis 4:14
The context
Genesis 4 narrates the first murder, the dialogue that follows, and the sentence on Cain. He protests that the punishment is more than he can bear, and he names a specific fear: that anyone who meets him will kill him. The mark that follows is given in response to that fear.
What it establishes
It establishes that the narrative has Cain anticipate blood vengeance from others, which implies a wider population and an operating custom of retribution. The fear is treated as reasonable enough to warrant protection.
What it does not establish
It does not identify those others. The passage creates a well-known narrative problem for a story that has so far named only a few people, and the text offers no explanation. Solutions involving other lines or earlier populations are inferences, not statements in the text.
