'Wholesome Words' in the Bible

Let no unwholesome words ever pass your lips, but let all your words be good for benefiting others according to the need of the moment, so that they may be a means of blessing to the hearers.

If any man teach otherwise, and consent not to wholesome words, even the words of our Lord Jesus Christ, and to the doctrine which is according to godliness;

See thou have the example of the wholesome words which thou heardest of me, in faith and love which is in Jesus Christ.
