Charles H. Spurgeon on Psalms 119:120

The fifteenth letter, SAMECH, denotes a prop or pillar, and this agrees well with the subject matter of the strophe, in which God is twice implored to uphold his servant (Psalms 119:16-17), while the utter destruction of those who make light of his law, or encourage scepticism regarding it, may be compared to the fate of the Philistine lords, on whom Samson brought down the roof of the house where they were making merry, by overthrowing the pillars which supported it. Neale and Littledale.

My flesh trembleth for fear of thee. Instead of exulting over those who fell under God's displeasure he humbleth himself. What we read and hear of the judgments of God upon wicked people should make us (1) To reverence his terrible majesty, and to stand in awe of him. Who is able to stand before this holy Lord God? 1 Samuel 6:20. (2) To fear lest we offend him, and become obnoxious to his wrath. Good men have need to be restrained from sin by the terrors of the Lord; especially when judgment begins at the house of God, and hypocrites are discovered, and put away as dross. Matthew Henry.

Ver 120. My flesh trembleth for fear of thee, etc. At the presence of Jehovah, when he appeareth in judgment, the earth trembleth and is still. His best servants are not exempted from an awful dread, upon such occasions; scenes of this kind, shown in vision to the prophets, cause their flesh to quiver, and all their bones to shake. Encompassed with a frail body, and a sinful world, we stand in need of every possible tie; and the affections both of fear and love must be employed, to restrain us from transgression; we must, at the same time, "love God's testimonies, and fear his Judgments." George Horne.

Ver. 120 My flesh trembleth for fear of thee, etc. In prayer, in the evening I had such near and terrific views of God's judgments upon sinners in hell, that my flesh trembled for fear of them...I flew trembling to Jesus Christ as if the flames were taking hold of me: Oh! Christ will indeed save me or else I perish. Henry Martyn, 1781-1812.
