A few verses later the writer of Ecclesiastes, King Solomon, sums up this verse by saying, ” It is better not to vow than to make a vow and not fulfill it.” (Ecclesiastes 5:5) We are not to be rash or hasty in our promises to God…that’s what Solomon called sacrifices of fools. Rather, we are to use self discipline…listening for that still small voice of the Holy Spirit in order to hear clearly what the Lord wants of us.
