Prepping advice in scripture. Proverbs 21:20 says: ” In the house of the wise are stores of choice food and oil; but the foolish man devours all he has”. this verse is deep. It speaks to the overall wisdom of prepping. The idea of having something more in your pantry than what you need for the next few days is very clear. Solomon recommends having “stores” of food. That is plural. There is no specific number of months worth of food mentioned , but I would say, do what you can.
