4:1-5 Every attempt to revive true religion will stir up the opposition of Satan, and of those in whom he works. The adversaries were the Samaritans, who had been planted in the land of Israel, 2Ki 17. It was plain that they did not mean to unite in the worship of the Lord, according to his word. Let those who discourage a good work, and weaken them that are employed in it, see whose pattern they follow.

3. But Zerubbabel and Jeshua … said … Ye have nothing to do with us to build an house unto our God—This refusal to co-operate with the Samaritans, from whatever motives it sprang, was overruled by Providence for ultimate good; for, had the two peoples worked together, familiar acquaintanceship and intermarriage would have ensued, and the result might have been a relapse of the Jews into idolatry. Most certainly, confusion and obscurity in the genealogical evidence that proved the descent of the Messiah would have followed; whereas, in their hostile and separate condition, they were jealous observers of each other's proceedings, watching with mutual care over the preservation and integrity of the sacred books, guarding the purity and honor of the Mosaic worship, and thus contributing to the maintenance of religious knowledge and truth.
