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:

¹³ Which things also we speak, not in the words which man's wisdom teacheth, but which the Holy Ghost teacheth; comparing spiritual things with spiritual.

¹⁷ For Christ sent me not to baptize, but to preach the gospel: not with wisdom of words, lest the cross of Christ should be made of none effect.
