Luke 6:31-36 – the lesson on giving without expecting to receive

Now philosophy seems to divide justice into three parts; one towards God, which is called piety; another towards our parents, or the rest of mankind; a third to the dead, that the proper rites may be performed. But the Lord Jesus passing beyond the oracle of the law, and the heights of prophecy, extended the duties of piety to those also who have injured us, adding, But love your enemies.

St. Ambrose
