I learn from this proverb to be careful, concise, and accurate with words. Sometimes it may even be best to not say anything at all. Many words involve the risk of sin. Dragging out a point is seldom necessary.
Matthew Pool wrote, “People that love and commonly use much talking, do frequently run into many miscarriages, because such people, for the most part, (lack) wisdom to order their words aright and speak hastily, without care and consideration.” He cites Ecclesiastes 5:3, “As a dream comes when there are many cares, so the speech of a fool when there are many words.”
Peter comes to mind. He often spoke before thinking and made himself look foolish and on one occasion Jesus even harshly rebuked him. When Jesus was transfigured on the mountain top Peter said to Jesus, “Lord, it is good for us to be here. If you wish, I will put up three shelters—one for you, one for Moses and one for Elijah.” (Matthew 17:4) Jesus ignored his request.
Just before that when “Jesus explained to his disciples that he would suffer many things at the hands of the elders, chief priests and teachers of the law, and that he must be killed and on the third day be raised to life. Peter took him aside and began to rebuke him. “Never, Lord!” he said. “This shall never happen to you!” Jesus turned and said to Peter, “Get behind me, Satan! You are a stumbling block to me; you do not have in mind the things of God, but the things of men.” (Matthew 16:21-23)
