The covenant of the pieces between God and Abraham follows the form of the suzerain covenant; what is significant is that Israel has no duties to uphold; the covenant is not conditional. Future covenants between Israel and God would be conditional. This is clearly expressed in , recited twice-daily as part of the foundational prayer, the Shema. This passage declares that as long as Israel is faithful to God it will be blessed with ample crops but should it follow other gods the land will not support it. The cost of not following this covenant is hard.
