If I sin, then thou markest me, And thou wilt not acquit me from mine iniquity.

That, if I did wrong, you would take note of it, and would not make me clear from sin:

Εαν αμαρτησω, με παραφυλαττεις, και απο της ανομιας μου δεν θελεις με αθωωσει.

If I sin, then thou markest me, and thou wilt not acquit me from mine iniquity.
