16 I also will do this to you: I will appoint terror over you, even consumption and fever, that shall consume the eyes, and make the soul to pine away; and you will sow your seed in vain, for your enemies will eat it. 17 I will set my face against you, and you will be struck before your enemies. Those who hate you will rule over you; and you will flee when no one pursues you. 18 “‘If you in spite of these things will not listen to me, then I will chastise you seven times more for your sins. 19 I will break the pride of your power, and I will make your sky like iron, and your soil like brass; 20 and your strength will be spent in vain; for your land won’t yield its increase, neither will the trees of the land yield their fruit. 21 “‘If you walk contrary to me, and won’t listen to me, then I will bring seven times more plagues on you according to your sins. 22 I will send the wild animals among you, which will rob you of your children, destroy your livestock, and make you few in number; and your roads will become desolate. 23 “‘If by these things you won’t be reformed to me, but will walk contrary to me; 24 then I will also walk contrary to you; and I will strike you, even I, seven times for your sins. 25 I will bring a sword upon you, that will execute the vengeance of the covenant; and you will be gathered together within your cities: and I will send the pestilence among you; and you will be delivered into the hand of the enemy.

Commentary on Leviticus 26:14-39

(Read Leviticus 26:14-39)

After God has set the blessing before them which would make them a happy people if they would be obedient, he here sets the curse before them, the evils which would make them miserable, if they were disobedient. Two things would bring ruin. 1. A contempt of God's commandments. They that reject the precept, will come at last to renounce the covenant. 2. A contempt of his corrections. If they will not learn obedience by the things they suffer, God himself would be against them; and this is the root and cause of all their misery. And also, The whole creation would be at war with them. All God's sore judgments would be sent against them. The threatenings here are very particular, they were prophecies, and He that foresaw all their rebellions, knew they would prove so. TEMPORAL judgments are threatened. Those who will not be parted from their sins by the commands of God, shall be parted from them by judgments. Those wedded to their lusts, will have enough of them. SPIRITUAL judgments are threatened, which should seize the mind. They should find no acceptance with God. A guilty conscience would be their continual terror. It is righteous with God to leave those to despair of pardon, who presume to sin; and it is owing to free grace, if we are not left to pine away in the iniquity we were born in, and have lived in.
