Genesis 4:13

“And Cain said unto the Lord, etc.] In the anguish of his spirit and the distress of his mind: my punishment is greater than I can bear; thus complaining of the mercy of God, as if he acted a cruel part, inflicting on him more than he could endure; and arraigning his justice, as if it was more than he deserved, or ought in equity to be laid on him; whereas it was abundantly less than the demerit of his sin, for his punishment was but a temporal one; for, excepting the horrors and terrors of his guilty conscience, it was no other than a heavier curse on the land he tilled, and banishment from his native place, and being a fugitive and wanderer in other countries; and if such a punishment is…”

“4:13-14 For Cain, eviction from the land—the domain of his vocation as a farmer (see 4:2; cp. 3:23)—amounted to exile from God’s presence. The Israelites were warned that unfaithfulness to the Sinai covenant would similarly result in eviction from the Promised Land and from God’s presence in the Temple (see, e.g., Lev 26:27-32).”

“My punishment is greater than I can bear. or, Mine iniquity is greater than that it may be forgiven. Job 15:22; Rev 16:9, Rev 16:11, Rev 16:21 Genesis 4:14”
