28:15-44 If we do not keep God's commandments, we not only come short of the blessing promised, but we lay ourselves under the curse, which includes all misery, as the blessing all happiness. Observe the justice of this curse. It is not a curse causeless, or for some light cause. The extent and power of this curse. Wherever the sinner goes, the curse of God follows; wherever he is, it rests upon him. Whatever he has is under a curse. All his enjoyments are made bitter; he cannot take any true comfort in them, for the wrath of God mixes itself with them. Many judgments are here stated, which would be the fruits of the curse, and with which God would punish the people of the Jews, for their apostacy and disobedience. We may observe the fulfilling of these threatenings in their present state. To complete their misery, it is threatened that by these troubles they should be bereaved of all comfort and hope, and left to utter despair. Those who walk by sight, and not by faith, are in danger of losing reason itself, when every thing about them looks frightful.

29-33. thou shalt grope at noonday—a general description of the painful uncertainty in which they would live. During the Middle Ages the Jews were driven from society into hiding-places which they were afraid to leave, not knowing from what quarter they might be assailed and their children dragged into captivity, from which no friend could rescue, and no money ransom them.
