Don't Speak Without Thinking

Proverbs 18:21

21 Death and life are in the power of the tongue: and they that love it shall eat the fruit thereof.

Proverbs 21:23
He who guards his mouth and his tongue, Guards his soul from troubles.

Matthew 12:36-37
36“But I tell you that every careless word that people speak, they shall give an accounting for it in the day of judgment. 37“For by your words you will be justified, and by your words you will be condemned.”

Romans 10:9

9 That if thou shalt confess with thy mouth the Lord Jesus, and shalt believe in thine heart that God hath raised him from the dead, thou shalt be saved. 10 For with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation. 11 For the scripture saith, Whosoever believeth on him shall not be ashamed. 12 For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him. 13 For whosoever shall call upon the name of the Lord shall be saved.
