Charles H. Spurgeon on Psalms 119:121

I have done judgment and justice. Here the view of David in his judicial capacity might present itself to us; and if so, we have David in the midst of large experience; for the words would take in a large portion of his life. How blessed were their reflections, if, after a long reign, all sovereign rulers could thus appeal unto God. It should be so; for to him all shall be accountable at last. Even although we only conceive of David as speaking in the character of a private man, the sentiment is worthy of all consideration... For parents to say this of their dealings with their children, masters of servants, a man of his neighbours, is very excellent. John Stephen.
