Albert Barnes on Philippians 2:14

Do all things without murmurings and disputings. In a quiet, peaceful, inoffensive manner. Let there be no brawls, strifes, or contentions. The object of the apostle here is, probably, to illustrate the sentiment which he had expressed in Php 2:3-5, where he had inculcated the general duties of humbleness of mind, and of esteeming others better than themselves. In order that that spirit might be fully manifested, he now enjoins the duty of doing every thing in a quiet and gentle manner, and of avoiding any species of strife. Eph 4:31, Eph 4:32.
