Brothers, I write no new commandment to you, but an old commandment which you had from the beginning. The old commandment is the word which you heard from the beginning.
"Fellowship" (Gr. koinonia) is the less common term occurring only four times in 1 John: 1 John 1:3 (twice), 6, 7. "Know" is more common. Ginosko (to know experientially) appears 24 times: 1 John 2:3-5; 1 John 2:13 (twice), 14, 18, 29; 1 John 3:1 (twice), 6, 16, 19, 20, 24; 1 John 4:2; 1 John 4:6 (twice), 7, 8, 13, 16; 1 John 5:2; 1 John 5:20. Oida (intellectual knowledge) appears 15 times: 1 John 2:11; 1 John 2:20-21 (twice), 29; 1 John 3:2; 1 John 3:5; 1 John 3:14-15; 1 John 5:13; 1 John 5:15 (twice), 18, 19, 20. The noun ginosis (experiential knowledge) is absent from this epistle.
