In Context

12 not as Cain — of the evil one he was, and he did slay his brother, and wherefore did he slay him? because his works were evil, and those of his brother righteous.

13 Do not wonder, my brethren, if the world doth hate you;

14 we — we have known that we have passed out of the death to the life, because we love the brethren; he who is not loving the brother doth remain in the death.

15 Every one who is hating his brother — a man-killer he is, and ye have known that no man-killer hath life age-during in him remaining,

16 in this we have known the love, because he for us his life did lay down, and we ought for the brethren the lives to lay down;

17 and whoever may have the goods of the world, and may view his brother having need, and may shut up his bowels from him — how doth the love of God remain in him?
