You belong to your father the devil, and you are [always] wanting to do what your father desires. He was a murderer from the [very] beginning [Note: This is probably a reference to Satan's influence on Adam, Eve and Cain in the Garden of Eden] and does not stand for the truth, because there is no truth in him. When he lies, he only speaks what is part of his nature, because he is a liar and the father of [all] liars.

By [having] faith, Abel offered to God a better sacrifice than Cain did. [And] because of his faith he was commended by God for being righteous, when God expressed approval of his offerings. By means of his faith, Abel still speaks [to us], even though he is dead.

not [hate each other] the way Cain did, who belonged to the evil one [i.e., Satan], when he murdered his brother [Abel]. And why did he murder him? It was because his [own] actions were evil and his brother's were righteous [See Heb. 11:4].

It is too bad for these people, for they have followed the example of Cain [the murderer]; for the sake of money they have rushed into the [same] error as Balaam committed [See Num. 25:1-5; 31:16]; they [will] perish [spiritually] for having rebelled [against God] like Korah did. [See Num. 16:1-3, 31-35].
