The answer is: Sihon

Deut 2:26,30

If you've ever delved into the heart of Deuteronomy, you'd know it's rich with adventure and substance. The episode involving Sihon, the king of Heshbon, is practically a miniature saga of its own! Sihon was an Amorite king who definitely wasn't in the mood to roll out the red carpet for the Israelites as they journeyed to the Promised Land.

Now, why would he be so opposed? It’s interesting to note that Heshbon, a city originally assigned to the Reubenites, had gone through several regime changes and was strategically located on the crossroads of trade routes. Imagine, with so many groups moving about, tensions were bound to brew! Sihon was not just protecting his territory but his careful investments in maintaining power over a vital trade center.

Notably, this encounter was not merely about territory; it really shed light on a larger theme of conflict and confrontation with other nations as the Israelites sought to realize their destiny. The Israelites, undoubtedly, would pray and prepare for battle, turning what began as a simple request for passage into a conflict with significant consequences that would echo throughout Israel's subsequent history.

Enchantingly, this part of Deuteronomy reminds us of narratives from other parts of the Bible — think of David facing Goliath or the ultimatums Noah faced before the Flood! Each story teaches resilience and divine support in moments of challenge, showcasing how clashes and dramas reveal deeper spiritual truths amidst human history.
