Luke 1:50
His mercy extends to those who fear him, from generation to generation — the mercy (eleos) of God extending across generations is the covenant faithfulness of the Old Testament — the hesed, the loving-kindness that forms Israel's theology of divine character. From generation to generation communicates that what God is doing in Mary's womb is not a new thing but the continuation of the covenant faithfulness that has characterized God's relationship with Israel across all generations.
