4:6-13 See the folly of carnal hearts; they wander from one creature to another, seeking for something to satisfy, and labour for that which satisfies not; yet, after all, they will not incline their ear to Him in whom they might find all they can want. Preaching the gospel is as rain, and every thing withers where this rain is wanting. It were well if people were as wise for their souls as they are for their bodies; and, when they have not this rain near, would go and seek it where it is to be had. As the Israelites persisted in rebellion and idolatry, the Lord was coming against them as an adversary. Ere long, we must meet our God in judgment; but we shall not be able to stand before him, if he tries us according to our doings. If we would prepare to meet our God with comfort, at the awful period of his coming, we must now meet him in Christ Jesus, the eternal Son of the Father, who came to save lost sinners. We must seek him while he is to be found.

cleanness of teeth—explained by the parallel, "want of bread." The famine alluded to is that mentioned in 2Ki 8:1 [Grotius]. Where there is no food to masticate, the teeth are free from uncleanness, but it is the cleanness of want. Compare Pr 14:4, "Where no oxen are, the crib is clean." So spiritually, where all is outwardly smooth and clean, it is often because there is no solid religion. Better fighting and fears with real piety, than peace and respectable decorum without spiritual life.
