Our words mean things. What we say is a reflection of our heart. G-d warns us that when we make a vow we must do what we say.
G-d has given me stern warnings about my tongue. HE has told me “don’t ever speak to me that way again.”
The power of life and death is in the tongue. G-d created the earth with ten utterances. This means what I say has an effect on very life itself.
HaShem told me control your tongue.
I am learning how to do this.
