{It is sanctified} (hagiazetai). Present passive indicative
of hagiaz(935c), here "rendered holy" rather than "declared holy."
Cf. verse  4 . {Through the word of God and prayers} (dia logou
theou kai enteuxe(9373)). See  2:1  for enteuxis. Paul seems to
refer to Genesis 1. It is almost a hendiadys "by the use of
Scripture in prayer."
