Deuteronomy 20:10 commands offering peace before attacking; Moses precisely follows that law in Deuteronomy 2:26 by sending peace messengers.

Deuteronomy 1:4 notes the defeat of Sihon, providing the outcome of the peace mission described here.

Matthew 10:12-15 instructs offering peace then judgment if rejected, mirroring Moses' offer to Sihon and his subsequent defeat in Deuteronomy 2:26ff.

Numbers 21:21 recounts the same event, Israel sending messengers to Sihon with a peace proposal.

Judges 11:19 retells the same event from Jephthah's speech, referencing Israel's request to Sihon.

Nehemiah 9:22 summarizes God giving Sihon's land to Israel, fulfilling the outcome of the peace offer.

Esther 9:30 describes sending letters 'with words of peace', the same phrase used for Moses' diplomatic mission in Deuteronomy 2:26.
