^18 (A)For if God's gift depends on the Law, then it no longer depends on his promise. However, it was because of his promise that God gave that gift to Abraham.

The Law was handed down by angels, with a man acting as a go-between. ²⁰ But a go-between is not needed when only one person is involved; and God is one.^[a]
