The word translated sorrow of heart is found no where else in holy writ, which makes a certain particular explication of it to be difficult, and hath given interpreters a strange liberty in translating it shield, sorrow, and grief, obstinacy or hardness of heart, perplexity, abjection or breaking of heart; the best guides we have to direct us in the sense of it are, 1. The other things joined with it; persecution, destruction, a recompence according to their works, so that some afflictive evil of a heavy nature is certainly signified by it. 2. The analogy of faith, which restraineth us from wishing or praying for spiritual or eternal evils against our worst enemies; it therefore probably signifies such perplexity and breakings of mind as commonly attend a state of great affliction.
