Exegesis:

hou charin, legō soi, apheōntai hai hamartiai autēs ‘therefore, I tell you, her sins have been forgiven,’ or, punctuating with Nestle hou charin legō soi, ‘therefore I tell you.’ The former suggests a somewhat stronger connexion between the woman’s behaviour and the forgiving of her sins, but it should be born in mind that the parable of vv. 41ff says that the measure of love shows the measure of forgiveness, instead of determining it. For legō soi cf. on 3.8. For apheōntai cf. on 5.20.

hai hamartiai autēs hai pollai lit. ‘her sins, the many.’ hai pollai is emphatic by position, cf. “her sins, her many sins” (The Four Gospels – a New Translation).

hoti ēgapēsen polu ‘because she loved much.’ The clause refers to the evidence, or proof, of the fact that the woman’s sins had been forgiven, as brought about by a rendering like ‘her great love proves, or, shows it’ (cf. Translator’s New Testament), i.e. that her many sins have been forgiven.

hō de oligon aphietai, oligon agapa ‘he who is forgiven little, loves little,’ i.e. shows little love. The present tense conveys the idea of a general principle and tends to soften the obvious inference for Simon.

Translation:

Some other renderings in line with the interpretation given in Exegesis are, ‘her sins, which are many, are forgiven; the proof of it is that she loves much, or, that-is-why her love is great’ (cf. Batak Toba), “the great love she has shown proves that her many sins have been forgiven” (Good News Translation), ‘if she shows much love, it is because she has been forgiven her many sins’ (Bible de Jérusalem, note), ‘this woman here has loved me greatly, that’s how you can recognize that God has forgiven (lit. that no more at all God is following/noticing/making-her-accountable-for) her many sins’ (Tboli).

Her sins … are forgiven, or, to avoid a passive, ‘she received forgiveness for her sins’ (Sranan Tongo), ‘God has forgiven her sins’ (cf. Tae’ 1933, and Tboli).

She loved. If an object is required it should be ‘me,’ cf. Tboli, An American Translation.

He who is forgiven little, or, ‘whoever the forgiveness of his-sins is small’ (Toraja-Sa’dan), ‘whoever receives small forgiveness’ (Pohnpeian), ‘if God has forgiven a person only a few sins.’
