'Consecrate' in the Bible

Now the Passover of the Jews was approaching, and many from the country went up to Jerusalem before Passover to purify themselves [ceremonially, so that they would be able to participate in the feast].

Sanctify them in the truth [set them apart for Your purposes, make them holy]; Your word is truth.

For their sake I sanctify Myself [to do Your will], so that they also may be sanctified [set apart, dedicated, made holy] in [Your] truth.
