The answer is: Horses, wives, money

Deut 17:16-17

In Deuteronomy 17:16-17, God lays out some intriguing guidelines for kings, particularly around the fascinating topic of what they shouldn’t have in abundance. When we dive deeper into these verses, we can see that the teachings transcend mere limitations—they carry profound lessons about leadership and the dangers of excess.

First up, horses! In the ancient world, owning many horses was a sign of power and wealth, often linked to military strength. But reliance on a massive cavalry could lead kings to trust more in their chariots than in divine guidance, emphasizing the importance of humility and faith over reliance on military prowess.

Next, the taboo against multiple wives reflects not just marital arrangements but social stability. Ancient kings often engaged in marriage alliances to secure peace, but too many wives could breed familial discord and distractions from just governance. We see echoes of this with kings throughout history; some, like Solomon, had many wives, leading him down ultimately misguided paths.

Finally, accumulating excessive wealth can be seen as creating separation from the very people leaders are meant to serve. The guidance reveals a call for leaders to prioritize the well-being of their citizens rather than their own bounty.

This call for moderation forms a larger context inviting anyone in a position of influence to practice humility and wisdom, reminding us of the age-old principle that true leadership is not found in possessions or power but in integrity and service. Simple wisdom, right? And Bible trivia—most monarchies today don't have rules quite like this!
