Paul speaks of the way a person behaves as if it were a road or path a person walks on. Alternate translation: "These are the things you used to do" (See: [[rc://en/ta/man/jit/figs-metaphor]])
Possible meanings are 1) "when you practiced these things" or 2) "when you lived among the people who disobey God" (See: [[rc://en/ta/man/jit/figs-metaphor]])
