Genesis 4:8-10 Douay-Rheims 1899 American Edition (DRA)
8 And Cain said to Abel his brother: Let us go forth abroad. And when they were in the field, Cain rose up against his brother Abel, and slew him.
9 And the Lord said to Cain: Where is thy brother Abel? And he answered, I know not: am I my brother's keeper?
10 And he said to him: What hast thou done? the voice of thy brother's blood crieth to me from the earth.
