1 Corinthians 1:17

For Christ sent me not to baptize, but to preach the gospel: not in wisdom of words, lest the cross of Christ should be made void. [A baptism is part of the commission (Matthew 28:19). Paul was sent to baptize; but it was not necessary that the apostle should administer the rite in person. It sufficed if he saw to it that it was done (John 4:2). Paul does not here mean to assert that he preached without study or forethought. His words must be construed in the light of the context; which show that he intends to deny that he encumbered the gospel message with any philosophical reasoning.]
