1 Corinthians 2:4-5

And my speech and my hachrazah (proclamation, kyrygma, preaching) to you of the Besuras HaGeulah of HASHEM was not in persuasive words but in the demonstration of the Ruach Hakodesh and the gevurat HASHEM (power of G-d), That the emunah (faith) of you may not be in the [Olam Hazeh] “chochmah” of Bnei Adam, but in the gevurat HASHEM.
