In Genesis 23:18, the purchase is finalized before the same witnesses — all who went in at the gate — closing the transaction opened at 23:10.

Genesis 34:24 uses nearly identical language — 'all that went out of the gate of his city' — echoing 'all that went in at the gate' here, describing the men gathered at the gate.

In Genesis 34:20, Hamor and Shechem also go to the city gate to address the gathered men — the same civic gathering-place setting as the Hittites' meeting here.

In Ruth 4:1-4, Boaz conducts a legal property transaction at the city gate before elders as witnesses — the same civic procedure Abraham follows here.

In Job 29:7, Job recalls sitting in the gate as a respected elder — the same gate-setting where civic authority and legal proceedings like Abraham's purchase took place.
