Charles H. Spurgeon on Psalms 119:159

Quicken me. Often as the Psalmist had repeated his prayer for quickening grace, *it was not a "vain repetition, "or an empty sound. Each time was it enlivened with abundant faith, intense feeling of his necessity, and the vehemency of most ardent affection. If the consciousness of the faintness of our strength and the coldness of our affections should lead us to offer this petition a hundred times a day in this spirit, it would never fail of acceptance. Charles Bridges. *Nine times is the petition urged, verses 25, 37, 40, 88, 107, 149 154, 156, and 159.
