English Standard Version, John 17:
This is a euphemism: Jesus consecrated/sanctified himself by going to the Cross. It alludes to the consecration in Exodus 13:19a for their sake I consecrate myself
After the Cross:2 Consecrate to me every firstborn male. The first offspring of every womb among the Israelites belongs to me, whether human or animal.
Today, believers may be sanctified in the truth of the Cross, Hebrews 10:19b they also may be sanctified in truth.
Jesus’s sanctification was the act of the Cross. Through it, we are sanctified by his blood.10 And by that will, we have been sanctified through the sacrifice of the body of Jesus Christ once for all.
