The answer is: By the fruit of his mouth

Pro 18:20

It’s fascinating how Proverbs taps into the timeless relationship between our words and our well-being. Here we find that a person's satisfaction isn't just tied to physical food or wealth, but rather the fruits of their speech—what they say and share. Proverbs 18:20 suggests that the very words we express have the power to nourish us.

Consider the implications! Our conversations can uplift or bring down; they can be instruments of peace or conflict. It's a delicate dance of communication; engaging positively not only enriches the lives of others but ours as well. Just harken back to the Gospel where we often see teachings around the idea that "out of the abundance of the heart, the mouth speaks" (Luke 6:45). It reinforces the idea that what we feed our minds will spill over into our discussions.

Digging deeper into biblical history, the concept of wisdom literature like Proverbs offers insights that date back thousands of years. Generous dialogue and thoughtful speech were prized virtues for many ancient cultures. And what’s more, cultural studies demonstrate that many societies believed respect and honesty in conversation water the seeds of community and trust.

By choosing our words thoughtfully—and perhaps speaking more fruitfully about kindness and wisdom—we cultivate a hunger that’s far greater than that for physical sustenance. Each conversation becomes a chance to 'till the soil' of our relationships, leading to fertile fields of mutual respect and understanding. Remember, laughter, encouragement, and thoughtfulness can feed our souls just as effectively as the bread on our tables!
