Even though Yahweh is everywhere, this idiom speaks of Cain as though he went far away. AT: "went away from where Yahweh spoke to him" (See: [[rc://en/ta/man/translate/figs-idiom]])
Your language may have a way of saying this politely. Some older versions say "knew." See how you translated this in [Genesis 4:1](./01.md). (See: [[rc://en/ta/man/translate/figs-euphemism]])
