She opens her mouth with wisdom. Wisdom causes her to open her mouth.How so? When she speaks, she speaks with wisdom.
You're changing the meaning of the text. It doesn't say "when she speaks she is wise".
Sure, but that has nothing to do with this verse.
Changing the meaning of the text is my point. is easy to take the NIV as she speaks wisdom. Esv, to me, shows she speaks because of wisdom.
As far as opening the mouth when you shouldn't.... The opposite of opening you mouth out of wisdom, would be opening you mouth unwisely. So, the comment is still valid and can be learned from this verse.
