Cain said, My punishment (Hebrews my sin) is greater than I can bear Sin, however, seems to be put for punishment, as it is Genesis 4:7, and in many other places. For Cain was not so sensible of his sin, as of the miserable effects of it, as appears from the next verse, where, to justify his complaint, he descants upon the sentence, observing, 1st, That he was excluded by it from the favour of God: that, being cursed, he was hid from God's face, which is indeed the true nature of God's curse, as they will find to whom God shall say, Depart from me, ye cursed. 2d, That he was expelled from all the comforts of this life; driven out from the face of the earth, and hid from God's face Shut out from the church, and not admitted to come with the sons of God to present himself before the Lord. And, adds he, every one that finds me shall slay me Wherever he goes, he goes in peril of his life. There were none alive but his near relations, yet even of them he is justly afraid, who had himself been so barbarous to his own brother.
