Psalms 119:113 - The Popular Commentary by Paul E. Kretzmann

I hate vain thoughts, literally, "wavering ones I hate," that is, those who are divided between two beliefs, those who waver in their loyalty, not knowing whether to turn to God or to false gods; but Thy Law do I love. People who are irresolute in their belief are, in away, more dangerous than out-and-out enemies of the truth; for their unionistic attitude is apt to influence such as are weak in faith. The best plan, therefore, is to have nothing to do with such spirits, but cling to the Word of God alone.
