In Acts 3:25, Peter tells Israelites they are heirs of the covenant and prophets God spoke to Abraham — directly linking the covenant here to the gospel promise.

Stephen retells this exact scene — God gave Abraham the covenant of circumcision — as part of his rehearsal of Israel's history before the Sanhedrin.

Isaiah 56:4 promises eunuchs who 'keep my Sabbaths' and 'choose what pleases me' and 'hold fast to my covenant' inclusion among God's people, extending the covenant pattern from Abraham.

Psalm 25:10 describes covenant-keepers receiving God's love and faithfulness, connecting 'keeping my covenant' from Abraham's covenant to the broader biblical pattern of covenant loyalty.

Psalm 103:18 blesses those who keep God's covenant, echoing the same principle from God's covenant with Abraham — covenant faithfulness brings God's enduring favor.
