*This metaphor compares a man building a house on rock to a person who lives his life based on the teachings of Jesus. (See: [[rc://en/ta/man/translate/figs-metaphor]])
"dug the foundation of the house deep enough to reach" or "built the house on solid rock." Some cultures may not be familiar with building on bedrock. In those cases, this could be translated in a more general way as in "set the house's foundation firmly in solid ground." (See: [[rc://en/ta/man/translate/figs-metaphor]])
