Genesis 4:11-21

11 And now thou cursed from the earth which has opened her mouth to receive thy brother's blood from thy hand.
12 When thou tillest the earth, then it shall not continue to give its strength to thee: thou shalt be groaning and trembling on the earth.
13 And Cain said to the Lord God, My crime too great for me to be forgiven.
14 If thou castest me out this day from the face of the earth, and I shall be hidden from thy presence, and I shall be groaning and trembling upon the earth, then it will be that any one that finds me shall slay me.
15 And the Lord God said to him, Not so, any one that slays Cain shall suffer seven-fold vengeance; and the Lord God set a mark upon Cain that no one that found him might slay him.
16 So Cain went forth from the presence of God and dwelt in the land of Nod over against Edem.
17 And Cain knew his wife, and having conceived she bore Enoch; and he built a city; and he named the city after the name of his son, Enoch.
18 And to Enoch was born Gaidad; and Gaidad begot Maleleel; and Maleleel begot Mathusala; and Mathusala begot Lamech.
19 And Lamech took to himself two wives; the name of the one was Ada, and the name of the second Sella.
20 And Ada bore Jobel; he was the father of those that dwell in tents, feeding cattle.
21 And the name of his brother was Jubal; he it was who invented the psaltery and harp.

Genesis 4:11-21 Meaning and Commentary

INTRODUCTION TO GENESIS 4

In this chapter an account is given of the two eldest children of Adam and Eve, their names and calling, Ge 4:1,2 and of their different offerings to the Lord, and the different respect had unto them by him, which in Cain issued in wrath and envy, which appeared in his countenance, and were taken notice of by the Lord, and about which he reasoned with him, Ge 4:3-7 but it had no effect upon him, he murdered his brother, upon which he was examined about him, but denied he knew anything of him where he was, Ge 4:8,9 he is arraigned, convicted and condemned, sentence passed upon him, and that executed, which he complains of, and is mitigated, or however a protection is granted him, and a mark set on him for his security, Ge 4:10-15 after which we have an account of his posterity for several generations, their names, and the business of some of them, Ge 4:16-24 and the chapter is closed with the birth of another son, and of a grandson to Adam and Eve, in whose days was the beginning of social religion.
