In Matthew 23:19, Jesus calls the altar that sanctifies the gift greater than the gift itself — reinforcing that proper worship requires right relationships.

Matthew 8:4 also mentions offering at the altar — there Jesus commands the leper to follow the Mosaic law, while here reconciliation takes priority.

In Leviticus 6:2-6, the law requires restitution before a guilt offering — directly paralleling Jesus' teaching that reconciliation must precede the gift at the altar.

In 1 Samuel 15:22, Samuel declares obedience better than sacrifice — the same priority Jesus applies here when he says reconcile before offering.

Isaiah 1:10-17 rejects sacrifices from wicked hands, calling for justice instead — directly parallel to Jesus insisting reconciliation precedes the gift.

Hosea 6:6 says God desires mercy not sacrifice — a key OT principle Jesus often quotes, and the same logic underlies this call to reconcile.

Amos 5:21-24 condemns empty worship without justice — mirroring Jesus' teaching that broken relationships invalidate offerings.

In Luke 19:8, Zacchaeus restores fourfold to those he defrauded — a practical example of making things right before continuing, exactly as Jesus teaches.
