Cross-reference
In Genesis 26:33, the place is named Beersheba — the naming follows directly from the oath sworn in this covenant between Isaac and Abimelech.
In Gen 21:22, Abimelech notes God is with Abraham — the precedent he cites in 26:28 as reason for his treaty with Isaac.
In Gen 21:23, Abimelech secures a covenant with Abraham — the direct model he invokes in 26:28 for his treaty with Isaac.
In Genesis 21:31, Abraham and Abimelech swore an oath at Beersheba — Isaac's covenant here directly repeats his father's earlier pact with the same leader.
In Genesis 21:27, Abraham and Abimelech make a covenant exchanging animals — Isaac's covenant directly mirrors his father's earlier pact with the same leader.
In Genesis 39:2, Potiphar sees the LORD was with Joseph — same pattern: an outsider recognizes God's presence with His servant.
In Genesis 39:3, Potiphar sees God's favor on Joseph and responds by elevating him — same theme of outsiders perceiving divine blessing.
In Genesis 21:32, Abimelech returns to Philistine territory after the treaty — same Abimelech party involved in both father's and son's covenants.

In Genesis 31:44, Jacob proposes a covenant with Laban — another Genesis covenant between parties seeking peaceful separation.
In 1 Corinthians 14:25, an outsider falls down and confesses 'God is really among you' — the NT mirror of Abimelech's confession here.
In Hebrews 6:16, people swear by someone greater to confirm agreements — this reflects the oath-confirming practice visible in Isaac's covenant.
In Hebrews 6:17, God confirms His promise with an oath — the same concept of binding sworn agreements seen here.
