Surely he shall deliver thee from the snare of the fowler, and from the noisome pestilence.
The word pictures behind "noisome pestilence" bring us to the realisation that to breathe is to exist.
Did you realise you cannot breathe in and speak at the same time?
In order to speak you must breathe out.
The question is: 'Are my words breathing peace or a plague upon myself and those around me?'
Lord deliver us from the "noisome pestilence" of our words.
