YLT(i)
5 and ye have known that he was manifested that our sins he may take away, and sin is not in him;
6 every one who is remaining in him doth not sin; every one who is sinning, hath not seen him, nor known him.
7 Little children, let no one lead you astray; he who is doing the righteousness is righteous, even as he is righteous,
8 he who is doing the sin, of the devil he is, because from the beginning the devil doth sin; for this was the Son of God manifested, that he may break up the works of the devil;
