John 17:17

KJV

Sanctify them through thy truth: thy word is truth.

NIV

Sanctify them by the truth; your word is truth.

The phrase “thy truth” specifically refers to God’s truth, not a generalized form of “the truth”. And because the second clause (in modern versions) does not say “your word is the truth”, there is a different shade of meaning implied- indicating that God’s word is part of a greater truth that can sanctify us, rather than giving the sense that God’s word is his truth and wholly sufficient in itself to sanctify us.
