4:1-6 Many a good work has been looked upon with contempt by proud and haughty scorners. Those who disagree in almost every thing, will unite in persecution. Nehemiah did not answer these fools according to their folly, but looked up to God by prayer. God's people have often been a despised people, but he hears all the slights that are put upon them, and it is their comfort that he does so. Nehemiah had reason to think that the hearts of those sinners were desperately hardened, else he would not have prayed that their sins might never be blotted out. Good work goes on well, when people have a mind to it. The reproaches of enemies should quicken us to our duty, not drive us from it.
