God’s will was communicated to the High Priest through the Urim and Tumim, the earliest recorded “voting device”, but generally in bible leadership was not achieved by democratic decision.
That said, bible gives us guidance about qualities in leaders, helping us decide how to use our votes.
Jethro advises Moses “Provide from the entire people able people who fear God, trustworthy and hating bribes…to be their rulers”(Ex 18), and Moses tells Israel “Take from every tribe men of wisdom, understanding and knowledge, and.. make them rulers over you. (Deut 1:13)
Hosea provides a picture of inappropriate government: “My people are destroyed for lack of knowledge” “They have set up kings, but not from Me, made princes, and I knew it not; of their silver and gold have they made idols” and warns of the consequences. Proverbs teaches “When the righteous are in authority, the people rejoice, but when the wicked rule, the people groan.(29:2) and reminds us of the perils of short termism: “The lip of truth shall be established for ever: but a lying tongue is but for a moment.”
So what do we learn? Political candidates should be from across the population rather than a political class; they should be trustworthy, able to understand their role and bring a knowledgeable mind to their work. They should have integrity; not be swayed by the interests of the wealthy or lobbyists, nor interested in material gain. They should be working for the benefit of the whole people and not prioritise short-term political gains above long term. And bible has another insight – we should watch who politicians associate with. “Make no friendship with an angry man; and with a furious man do not go: Lest you learn their ways, and get a snare to thy soul.” Because “when the wicked rise, people hide themselves away”
