10
Anyone who loves their brother and sister[a] lives in the light, and there is nothing in them to make them stumble.
11
But anyone who hates a brother or sister is in the darkness and walks around in the darkness. They do not know where they are going, because the darkness has blinded them.
[a].
The Greek word for "brother and sister" ("adelphos" ) refers here to a believer, whether man or woman, as part of God’s family; also in 3:10; 4:20, 21.
