It's the community!

Torah provided the means for them to be in relationship with Yahweh through the covenant; it did not reconcile them to God by permanently obliterating their sin. (Reconciliation to God is another concept that is absent from Old Testament theology, except in regard to restoration of favor following covenant infidelity.) Individuals could be faithful to the covenant, and that put them in good standing in the covenant community, a community that continued to exist in covenant relationship with Yahweh generation to generation, though individuals would come and go. Individuals who failed to observe the Torah could be cut off from the community so that they would not negatively affect the good standing of the community as God’s people. If the community as a whole failed to keep the covenant, the covenant curses would come upon them and they could lose the covenant benefits (land and the privilege of Yahweh dwelling among them) and instead suffer exile.—Walton and Walton, The Lost World of the Torah, 159
