Charles H. Spurgeon on Psalms 119:25

My soul cleaveth unto the dust, etc. The word rendered "cleaveth" means to be glued to; to stick fast. It has the sense of adhering firmly to anything, so that it cannot easily be separated from it. The word "dust" here may mean either the earth, and earthly things, considered as low, base, unworthy, worldly; or it may mean the grave, as if he were near to that, and in danger of dying. De Wette understands it in the latter sense. Yet the word cleave would hardly suggest this idea; and the force of that word would be better represented by the idea that his soul, as it were, adhered to the things of earth, that it seemed to be so fastened to them so glued to them that it could not be detached from them; that his affections were low, earthly, grovelling, so as to give him deep distress, and lead him to cry to God for Life and strength that he might break away from them. Albert Barnes.
