John 17:19

“And for their sakes I sanctify myself, etc.] Which is to be understood, not of his making himself holy; for he never was a sinner, and so stood in no need of sanctification: he was made like unto us, yet without sin; he looked like a sinner, but was not one; he was traduced, charged, and treated as such, but was perfectly holy, and free from all sin; he was essentially and infinitely holy as God; and as man, he was holy in his conception and birth; he was filled with the Holy Ghost, and was holy in his life and in his death: rather this may be meant of his being separated, and set apart for his office as Mediator, which, though done by the Father, and is ascribed unto him, (<431036>John…”

“And for their sakes I sanctify--consecrate. myself that they also might--may. be sanctified--consecrated. The only difference between the application of the same term to Christ and the disciples is, as applied to Christ, that it means only to "consecrate"; whereas, in application to the disciples, it means to consecrate with the additional idea of previous sanctification, since nothing but what is holy can be presented as an offering.

“I sanctify myself - I devote myself as a victim, to be sacrificed. John 17:20”

“17:19 I give myself as a holy sacrifice (literally I sanctify myself): Priests and prophets were similarly set apart for service to God (Lev 8:30; Jer 1:5). Jesus recommitted himself to his mission, acknowledging that he was set apart for the purpose of the cross. The disciples would benefit because his death would enable them to experience new holiness in a deep attachment to God.”

“for: Isa 62:1; Co2 4:15, Co2 8:9; Th1 4:7; Ti2 2:10 I sanctify: Joh 10:36; Jer 1:5; Co1 1:2; Heb 2:11, Heb 9:13, Heb 9:18, Heb 9:26, Heb 10:5-10, Heb 10:29 that: Joh 17:17; Tit 2:14 sanctified through the truth: or, truly sanctified John 17:20”
