4. The people conformed to the example of the king, nay, it should seem, they led the way, for they first began to put on sackcloth, from the greatest of them even to the least of them, v. 5. The least of them, that had least to lose in the overthrow of the city, did not think themselves unconcerned in the alarm; and the greatest of them, that were accustomed to lie at ease and live in state, did not think it below them to put on the marks of humiliation. The wearing of sackcloth, especially to those who were used to fine linen, was a very uneasy thing, and they would not have done it if they had not had a deep sense of their sin and their danger by reason of sin, which hereby they designed to express. Note, Those that would not be ruined must be humbled, those that would not destroy their souls must afflict their souls; when God's judgments threaten us we are concerned to humble ourselves under his mighty hand; and though bodily exercise alone profits nothing, and man's spreading sackcloth and ashes under him, if that be all, is but a jest (it is the heart that God looks at, Isa. lviii. 5), yet on solemn days of humiliation, when God in his providence calls to mourning and girding with sackcloth, we must by the outward expressions of inward sorrow glorify God with our bodies, at least by laying aside their ornaments.
