Charles H. Spurgeon on Psalms 119:108

The freewill offerings of my mouth. This place makes known that species of sacrifices, which neither tribulations nor poverty of means can hinder, and which does not require an external temple, but in desert places and among heathen may be offered by a godly man. And these sacrifices of the mouth God himself makes more of than if all the flocks of the whole earth had been offered to him, and all the treasures of gold, and of silver, and of precious stones. Wolfgang Musculus.
