Matthew Poole and continuators on Genesis 27:38

38 And Esau said unto his father, Hast thou but one blessing, my father ? bless me, even me also, O my father. And Esau lift up his Voice, and wept.

By which words Esau manifests his profane and worldly mind, that he esteemed this Blessing but as one among many others equal to it, and did not apprehend the true and peculiar excellency and absolute necessity of it, and that it was impossible for him or his posterity to be happy without an interest in this covenant and continuance in that Church to which it was appropriated.
