A.T. Robertson Commentary Luke 13:5

"I tell you, Nay: but, except ye repent, ye shall all likewise perish." — Luke 13:5 (ASV)

Except ye repent (εαν μη μετανοησητε). First aorist active subjunctive, immediate repentance in contrast to continued repentance, μετανοητε in verse 3, though Westcott and Hort put μετανοητε in the margin here. The interpretation of accidents is a difficult matter, but the moral pointed out by Jesus is obvious.
