If I had not come and spoken unto them, they had not had sin: but now they have no excuse for their sin.

If I had not come and been their teacher they would have had no sin: but now they have no reason to give for their sin.

Εαν δεν ηλθον και ελαλησα προς αυτους, αμαρτιαν δεν ηθελον εχει· τωρα ομως δεν εχουσι προφασιν περι της αμαρτιας αυτων.

If I had not come and spoken unto them, they had not had sin: but now they have no cloke for their sin.
