Cry unto her; proclaim it in my name. Her warfare; the time of her servitude, and captivity, and misery. Her iniquity is pardoned; I am reconciled to her; I will not impute sin to her, to punish her any longer for it. Double for all her sins; not twice as much as her sins deserved, for she herself confessed the contrary, Ezra 9:13 Lamentations 3:22; but abundantly enough to answer God's design in this chastisement, which was to humble and reform them, and to warn others by their example. Double is oft put for abundantly, as Isaiah 61:7 Jeremiah 16:18, Jeremiah 17:18. God here speaks of himself after the manner of men, and compareth himself to a tender-hearted father, who when he hath corrected his child for his misdemeanour, relenteth and repenteth of his severity, and casteth his rod away.
