John 14:16
KJV
And I will pray the Father, and he shall give you another Comforter, that he may abide with you for ever;
NIV
And I will ask the Father, and he will give you another advocate to help you and be with you forever—
See also: John 14:26, 15:26, 16:7. Changing “Comforter” to other titles alters the nature of this particular role that Jesus is assigning to the Holy Spirit as he prepares his disciples for his leaving them. Take a moment to study the surrounding context, and you’ll see why “Comforter” fulfills this role so well: John 14:1,27, 15:18-20, 16:1-2,20-22,33. It also causes a disconnect from John 14:18 where the KJV says Jesus will not leave his disciples “comfortless” (although that word is also changed in modern versions).
