From Jesus Calling:
Be quick to listen, slow to speak and slow to anger. Words have such great power to bless or wound, therefore you should watch your words carefully. Ask my Holy Spirit to help you and guide you when you speak.
Reckless words pierce like a sword, but the tongue of the wise brings healing.
Proverbs 12:18
Holy Spirit, transform my mind and speak through me so that others may be healed and blessed. Amen
