2 And I, brethren, when I came to you, came not with excellency of speech or of wisdom, declaring unto you the testimony of God.

⁴ And my speech and my preaching was not with enticing words of man's wisdom, but in demonstration of the Spirit and of power:

⁵ For our gospel came not unto you in word only, but also in power, and in the Holy Ghost, and in much assurance; as ye know what manner of men we were among you for your sake.
