26:3-39 These blessings and curses resemble a key element of ancient Near Eastern suzerain-vassal treaties. In such treaties, the suzerain king promised to defend the vassal king and his state, while the vassal took an oath of loyalty to his lord. Blessings and curses followed, with the curses generally being more lengthy (contrast 26:3-13 with 26:14-39; cp. Deut 27:15–28:68). Such treaties would call upon the gods as witnesses and enforcers. In God’s covenant with Israel, however, the Lord was one of the parties to the treaty (Israel being the other); since the Lord could swear by no one greater, he swore by himself (see Gen 22:16; Heb 6:13). 26:3 Treaties and covenants had conditions attached to them. Israel’s blessings were conditioned on the people’s obedience to the terms revealed by God, to whom they had sworn obedience (Exod 24:7; Josh 24:21-22). The covenant itself, however, was irrevocable (Lev 26:44-45; see Rom 11:29); Israel could not cancel it. The people had only two choices: obedience, which brought blessing, or rebellion, which brought curse.
