Blessing and cursing should not come forth from the same mouth.
God wants us to bless others. We are not supposed to be cursing at people or cursing when we speak.
Ephesians 4v29 tells us that no corrupt communication should proceed out of our mouths. and James 3v13 says that we should share good conversation using wisdom.
We should be sharing words that help teach people holiness. Our speech should give grace to those who hear what we have to say.
Words from the KJV James Chapter 3 – “8 But the tongue can no man tame; it is an unruly evil, full of deadly poison.
9 Therewith bless we God, even the Father; and therewith curse we men, which are made after the similitude of God.
10 Out of the same mouth proceedeth blessing and cursing. My brethren, these things ought not so to be.
11 Doth a fountain send forth at the same place sweet water and bitter?
12 Can the fig tree, my brethren, bear olive berries? either a vine, figs? so can no fountain both yield salt water and fresh.
13 Who is a wise man and endued with knowledge among you? let him shew out of a good conversation his works with meekness of wisdom.”
