Luke 7:50

εἶπεν δὲ πρὸς τὴν γυναῖκα· ἡ πίστις σου σέσωκέν σε· πορεύου εἰς εἰρήνην.

And/so/then he said to the woman, your faith has saved you, go in peace.


 * postpositive δὲ
 * notice πρὸς τὴν γυναῖκα. Why did't the author use the dative without a preposition, which would also work. Is this a case of languages simplifying over time?
 * σέσωκέν - perfect. Meaning, her salvation is a done deal, but with ongoing circumstances?
 * πορεύου - 2P sg imperative
