[Mad Dawg]

σωφροσύνης is (of) chastity? I would have guessed "temperance"or moderation.

I love learning when I'm wrong.

"σωφροσύνης is (of) chastity? I would have guessed "temperance"or moderation."

You would have guessed right. The word can also mean prudence. It is translated "chastity" here to demonstrate self control. There a many Greek words with shades of meaning which don't translate into English well. The final word of the Our Father, πονηρός (as in ἀπὸ τοῦ πονηροῦ), is a good example of this.
