NET

13 But when he, the Spirit of truth, comes, he will guide you into all truth. For he will not speak on his own authority, but will speak whatever he hears, and will tell you what is to come.

Darby

13 But when *he* is come, the Spirit of truth, he shall guide you into all the truth: for he shall not speak from himself; but whatsoever he shall hear he shall speak; and he will announce^D7644 to you what is coming.

Darby Bible Notes

announce - The Greek has the sense of 'reporting,' 'bringing back a report.' Here I conceive because it is a message brought from another.

KJV

13 “Howbeit when he, the Spirit of truth, is come, he will guide you into all truth: for he shall not speak of himself; but whatsoever he shall hear,” [that] “shall he speak: and he will shew you things to come.”

Strong's

13 Howbeit ^G1161 when^G3752 he^G1565, the Spirit^G4151 of truth^G225, is come^G2064, he will guide^G3594 you^G5209 into^G1519 all^G3956 truth^G225: for^G1063 he shall^G2980 not^G3756 speak^G2980 of^G575 himself^G1438; but^G235 whatsoever^{G3745 G302} he shall hear^G191, that shall he speak^G2980: and^G2532 he will shew^G312 you^G5213 things to come^G2064.
