John 17:19 ASV

¹⁷  Sanctify them in the truth: thy word is truth.

¹⁸  As thou didst send me into the world, even so sent I them into the world.

¹⁹  And for their sakes I sanctify myself, that they themselves also may be sanctified in truth.

²⁰  Neither for these only do I pray, but for them also that believe on me through their word;

²¹  that they may all be one; even as thou, Father, 'art' in me, and I in thee, that they also may be in us: that the world may believe that thou didst send me.
