1 Thessalonians 2:3-5

Mace(i) 3 for our doctrine was free from all imposture, avarice, and fraud. 4 we preach the gospel just as God thought fit to intrust it with us, not being studious to please men, but God, who approves our sincerity. 5 our address to you was without any flattery, as you yourselves can witness, and God is witness that we had no avarice to disguise.
