But I'm open to being persuaded.
Consider Pss. 105-106. The covenant with Abraham is the covenant confirmed with Israel pertaining to the land. It was on the basis of this covenant that Israel was brought out of Egypt, preserved in the wilderness, and given the lands of the heathen, Ps. 105. By the same covenant kindness, loyalty, and mercy, Israel was repeatedly delivered notwithstanding her continual covenant-breaking and rebellion, Ps. 106.
