No God-fearing husband can truthfully say he loves his wife if he willfully injuries her with his words.
{ Colossians 3:19}

Of course, the same would be true of a wife who verbally batters her husband.

Really,
it is an obligation of both mates to follow Paul's admonition to the Ephesians;
" Let a rotten saying not proceed out of your mouth,
but whatever saying is good for building up as the need may be,
that it may impart what is favorable to the hearers."
{ Ephesians 4:29}

Yes,the power of a kind word..
" A heart bowed down with anxiety, how a kind word can refresh it !
{ Proverbs 12:25 }

Recognizing the power of speech.
