Rock and Quarry
The 'rock' and 'quarry' refer to Abraham and Sarah, the forebears of the Israelites, symbolizing the origins and foundation of God's chosen people.
This imagery emphasizes God's faithfulness and the continuity of His covenant promises from the patriarchs to their descendants.
In ancient times, rocks and quarries were seen as sources of strength and stability, reflecting the enduring nature of God's promises.
