Luke 1:71-73

God’s redeeming work would involve salvation, mercy, and covenant fulfillment. Messiah’s salvation would be political and spiritual (cf. Psalms 106:10). God would be merciful to the fathers by fulfilling His promises to them (cf. Malachi 4:6). The oath God swore to Abraham refers to Genesis 22:16-18 that included promises of victory over enemies and universal blessing (cf. Genesis 26:3; Psalms 106:45). The words "covenant" and "oath" are central in the chiasm, as mentioned earlier. Note the repetition of the other key words or phrases in the chiasm in the surrounding verses. These are "come" or "visit," "his people," "salvation," "hand of our enemies," and "fathers."
