NIV
Live in harmony with one another; do not be haughty (snobbish, high-minded, exclusive), but readily adjust yourself to [people, things] and give yourselves to humble tasks. Never overestimate yourself or be wise in your own conceits. [Prov. 3:7.]AMP
Be of the same mind one toward another. Mind not high things, but condescend to men of low estate. Be not wise in your own conceits.
KJV
If it is to encourage, then give encouragement; if it is giving, then give generously; if it is to lead, do it diligently; if it is to show mercy, do it cheerfully.

He who exhorts (encourages), to his exhortation; he who contributes, let him do it in simplicity and liberality; he who gives aid and superintends, with zeal and singleness of mind; he who does acts of mercy, with genuine cheerfulness and joyful eagerness.
AMP
Or he that exhorteth, on exhortation: he that giveth, let him do it with simplicity; he that ruleth, with diligence; he that sheweth mercy, with cheerfulness.
