2 Samuel 21:3

Wherefore David said unto the Gibeonites, What shall I do for you? and wherewith shall I make the atonement, that ye may bless the inheritance of the Lord?

Cross-reference

2 Samuel 24:21 describes David buying a threshing floor to build an altar and stop a plague — another instance of David making atonement for the inheritance.

Exodus 32:30 shows Moses seeking to make atonement for Israel's sin — directly paralleling David's question about atoning for Saul's sin.

Hebrews 9:22 establishes that atonement requires bloodshed — the same principle underlying David's question about making propitiation for bloodguilt.

Leviticus 1:4 describes atonement through animal sacrifice — contrasting with the human blood atonement David will provide to the Gibeonites.

Micah 6:6 Parallel

Micah 6:6 echoes David's question with 'With what shall I come before the Lord?' — both ask what offering is required to approach God.
