Sihon

Sihon is cited here as a recent military victory — his defeat establishes Israel's credibility and momentum as Moses begins his address, showing that God has already started delivering on His promises.

Sihon is introduced as the recipient of Israel's peace offer — Moses addresses him diplomatically, requesting only safe passage through his territory with payment for any food or water used.

Sihon is invoked at the opening of the Og campaign as the precedent — God's promise to deliver Og uses Sihon's defeat as the explicit model.

Sihon is the first king catalogued in the eastern victory record — the Amorite ruler of Heshbon whose vast territorial holdings were the first major prize taken under Moses.

Sihon is referenced here as the Amorite king whose entire kingdom — including the capital Heshbon — Moses had already defeated and distributed to the eastern tribes.

Sihon is introduced here as the Amorite king who receives Israel's diplomatic request to pass through peacefully — a reasonable ask he will fatally miscalculate by refusing and marching out to war.

Sihon's former kingdom is the territory Moses is now distributing — his defeat by Israel was what made this eastern land available in the first place, and his capital Heshbon becomes Reuben's.

Sihon is invoked here to identify Gilead's historical pedigree — this territory once belonged to the Amorite king Israel defeated on its way to the Promised Land, now peacefully integrated into Solomon's kingdom.

Sihon is the first of two named kings destroyed in the conquest narrative — the Amorite ruler who blocked Israel's path and was defeated, his defeat cited as proof of God's protecting love.
