How can Lazarus Rise Again? (John 11:23–24)
The “etymological error” is defining a word by it morphemes, its little parts. There are times when context supports that a word still carries the meaning of its parts. εἰσέρχομαι (εἰς + πορεύομαι) means “to go into.” ἐξέρχομαι (ἐξ + ἔρχομαι) means “to go out.” But we can’t assume this is always the case. Context must support the etymological meaning. This is a common rule in exegesis, which is why the standard translation of our passage mystifies me.
