If the children of Israel did not listen to the voice of Jehovah their God and were not certain to do all His commandments and His statutes, all the curses would come upon them and overtake them (v. 15).
Verses 16 through 19 indicate that curses would come to every place, on everything, and in every way. They would be cursed in the city and in the field, and cursed in their coming in and in their going out. The curse would come on their basket and kneading bowl, on the fruit of their womb and of their ground, and on the offspring of their cattle and the young of their flock.
Verses 20 through 22 speak of curses in discomfiture in all undertakings, in a plague, in consuming diseases, in burning heat and drought, and in blight and mildew. The diseases here would not come and go but would cling to the people until they were consumed from off the land.
Other curses would be the heaven above their head becoming brass and the land under them becoming iron (v. 23). Moreover, Jehovah would make the rain of their land powder and dust (v. 24). How terrible!
The children of Israel would also be cursed in being struck down before their enemies and in all the diseases, robbings, and sufferings incurred at their hands (vv. 25-35).
