{Establishes} (ebai(936e)). Present active participle from
ebaios, firm. An apt metaphor in Corinth where confirmation of
a bargain often took place (ebai(9373)is) as Deissmann shows
(_Bible Studies_, p. 109) and as verse  22  makes plain.
{Anointed} (chrisas). From chri(935c), to anoint, old verb, to
consecrate, with the Holy Spirit here as in  1Jo 2:20 .
