The Greek noun brochē (βροχή) means rain or a shower of rain. It is derived from the verb brechō (G1026, to rain/wet) and appears only twice in the New Testament (Matthew 7:25, 27), in the parable of the two builders. The word describes the rain that falls on both the house built on rock and the house built on sand — the same rain that tests both foundations.
Jesus's parable of the two builders in Matthew 7:24-27 concludes the Sermon on the Mount and hinges on the word brochē. The same rain falls on both houses — the difference is entirely the foundation. The one who hears Jesus's words and does them has built on rock; the one who hears without obeying has built on sand. Brochē represents the storms of life — trials, persecution, doubt, temptation — that inevitably come to every person. The Gospel does not promise storm-free living but storm-proof foundations. The "rain" tests what was there all along. Christ alone is the Rock that does not shift.
