Let There Be No Jarring Note
Allow nothing like strife or dissension to come into the home. Speak gently. Never raise your voice to harshness. Keep yourselves calm. Put away faultfinding and all untruthfulness. Tell the children that you want to help them to prepare for a holy heaven, where all is peace, where not one jarring note is heard. Be patient with them in their trials, which may look small to you but which are large to them. When fathers and mothers are converted, there will be a thorough conversion of their principles of management. Their thoughts will be converted; their tongues will be converted.... There will be no loud, angry talking in the home. The words will be of a character to soothe and bless the hearer.... Take all the ugly features out of the voice. We must subdue a hasty temper and control our words, and in this we shall gain great victories. Unless we control our words and temper, we are slaves to Satan. We are in subjection to him. He leads us captive. All jangling and unpleasant, impatient, fretful words are an offering presented to his satanic majesty. And it is a costly offering, more costly than any sacrifice we can make for God; for it destroys the peace and happiness of whole families, destroys health, and is eventually the cause of forfeiting an eternal life of happiness.

John 10:10 KJV
