3. Mose 26:25

He would bring over them "the sword avenging (i.e., executing) the covenant vengeance." The "covenant vengeance" was punishment inflicted for a breach of the covenant, the severity of which corresponded to the greatness of the covenant blessings forfeited by a faithless apostasy. If they retreated to their towns (fortified places) from the sword of the enemy, the Lord would send a plague over them there, and give those who were spared by the plague into the power of the foe. He would also "break in pieces the staff of bread," and compel them by the force of famine to submit to the foe. The means of sustenance should become so scarce, that ten women could bake their bread in a single oven, whereas in ordinary times every woman would require an oven for herself; and they would have to eat the bread which they brought home by weight, i.e., not as much as every one pleased, but in rations weighed out so scantily, that those who ate would not be satisfied, and would only be able to sustain their life in the most miserable way. Calamities such as these burst upon Israel and Judah more than once when their fortified towns were besieged, particularly in the later times of the kings, e.g., upon Samaria in the reign of Joram (Kg2 6:25.), and upon Jerusalem through the invasions of the Chaldeans (cf. Isa 3:1; Jer 14:18; Eze 4:16; Eze 5:12).

This chapter is a solemn conclusion of the main body of the levitical law. The precepts that follow in this and the following book either relate to some particular matters or are repetitions and explications of the foregoing institutions. Now this chapter contains a general enforcement of all those laws by promises of reward in case of obedience on the one hand, and threatenings of punishment for disobedience on the other hand, the former to work upon hope, the latter on fear, those two handles of the soul, by which it is taken hold of and managed. Here is, I. A repetition of two or three of the principal of the commandments (Lev 26:1, Lev 26:2). II. An inviting promise of all good things, if they would but keep God's commandments (Lev 26:3-13). III. A terrible threatening of ruining judgments which would be brought upon them if they were refractory and disobedient (v. 14-39). IV. A gracious promise of the return of mercy to those of them that would repent and reform (Lev 26:40, etc.). Deu. 28 is parallel to this.
