Charles H. Spurgeon on Psalms 39:9

Because thou didst it. This holy man had a breach made both at his body and spirit at this time; he was sick and sad; yet he remembers from whose hand the blow came. Thou, Lord, didst it; thou, whom I love dearly, and so can take it kindly; thou whom I have offended, and so take it patiently; yea, thou, who mightest have cast me into a bed of flames, instead of my bed of sickness, and therefore I accept thy correction thankfully. Thus he catches at the blow without retorting it back upon God by any quarrelling discontented language. William Gurnall.
