5:19-31 Unhumbled hearts are ready to charge God with being unjust in their afflictions. But they may read their sin in their punishment. If men will inquire wherefore the Lord doeth hard things unto them, let them think of their sins. The restless waves obeyed the Divine decree, that they should not pass the sandy shores, which were as much a restraint as lofty mountains; but they burst all restraints of God's law, and were wholly gone into wickedness. Neither did they consider their interest. While the Lord, year after year, reserves to us the appointed weeks of harvest, men live on his bounty; yet they transgress against him. Sin deprives us of God's blessings; it makes the heaven as brass, and the earth as iron. Certainly the things of this world are not the best things; and we are not to think, that, because evil men prosper, God allows their practices. Though sentence against evil works is not executed speedily, it will be executed. Shall I not visit for these things? This speaks the certainty and the necessity of God's judgments. Let those who walk in bad ways consider that an end will come, and there will be bitterness in the latter end.
19. Retribution in kind. As ye have forsaken Me (Jer 2:13), so shall ye be forsaken by Me. As ye have served strange (foreign) gods in your land, so shall ye serve strangers (foreigners) in a land not yours. Compare the similar retribution in De 28:47, 48.
