1 Thessalonians 2:4-6 New King James Version (NKJV)

4 But as we have been approved by God to be entrusted with the gospel, even so we speak, not as pleasing men, but God who tests our hearts. 5 For neither at any time did we use flattering words, as you know, nor a [a]cloak for covetousness—God is witness. 6 Nor did we seek glory from men, either from you or from others, when we might have made demands as apostles of Christ.
