Treaties and covenants had conditions. Israel's blessings depended on the people's obedience to God's terms, to whom they had sworn obedience (Exodus 24:7; Joshua 24:21–22). But the covenant itself was unchangeable (Leviticus 26:44–45; see Romans 11:29). Israel could not cancel it. The people had two choices: obedience, which brought blessings; or rebellion, which brought curses.
