16 This will I do to you: I will put fear in your hearts, even wasting disease and burning pain, drying up the eyes and making the soul feeble, and you will get no profit from your seed, for your haters will take it for food. 17 And my face will be turned from you, and you will be broken before those who are against you, and your haters will become your rulers, and you will go in flight when no man comes after you. 18 And if, even after these things, you will not give ear to me, then I will send you punishment seven times more for your sins. 19 And the pride of your strength will be broken, and I will make your heaven as iron and your earth as brass; 20 And your strength will be used up without profit; for your land will not give her increase and the trees of the field will not give their fruit. 21 And if you still go against me and will not give ear to me, I will put seven times more punishments on you because of your sins. 22 I will let loose the beasts of the field among you, and they will take away your children and send destruction on your cattle, so that your numbers will become small and your roads become waste. 23 And if by these things you will not be turned to me, but still go against me; 24 Then I will go against you, and I will give you punishment, I myself, seven times for all your sins. 25 And I will send a sword on you to give effect to the punishment of my agreement; and when you come together into your towns I will send disease among you and you will be given up into the hands of your haters.

Matthew Henry's Commentary on Leviticus 26:16-25

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.
