1 Though I speak with the tongues of men and of angels, and have not charity, I am become as sounding brass, or a tinkling cymbal. 1 Corinthians 13:1 KJV https://bible.com/bible/1/1co.13.1.KJV
“He that keepeth his mouth keepeth his life: But he that openeth wide his lips shall have destruction.”
Proverbs 13:3 KJV
Death and life are in the power of the tongue: And they that love it shall eat the fruit thereof. Whoso findeth a wife findeth a good thing , And obtaineth favour of the LORD . The poor useth intreaties; But the rich answereth roughly. A man that hath friends must shew himself friendly: And there is a friend that sticketh closer than a brother. Proverbs 18:21-24 KJV https://bible.com/bible/1/pro.18.21-24.KJV
Pleasant words are as an honeycomb, Sweet to the soul, and health to the bones. Proverbs 16:24 KJV https://bible.com/bible/1/pro.16.24.KJV
In the multitude of words there wanteth not sin: but he that refraineth his lips is wise. The tongue of the just is as choice silver: the heart of the wicked is little worth. The lips of the righteous feed many: but fools die for want of wisdom.
Proverbs 10:19-21 KJV
