Ephesians 4:29

4:29 You must let no unwholesome word come out of your mouth, but only what is beneficial for the building up of the one in need, that it may give grace to those who hear.

Ephesians 6:6

6:6 not like those who do their work only when someone is watching – as people-pleasers – but as slaves of Christ doing the will of God from the heart.
