1 Corinthians 10:24

but that we write to them that they abstain from things contaminated by idols and from sexual immorality and from what is strangled and from blood.

Each of us is to please his neighbor for his good, to his building up.

it does not act unbecomingly, does not seek its own, is not provoked, does not take into account a wrong suffered;

Here for this third time I am ready to come to you, and I will not be a burden to you; for I do not seek what is yours, but you. For children ought not to save up for their parents, but parents for their children.

For they all seek after their own interests, not those of Christ Jesus.
