Charles H. Spurgeon on Psalms 39:9

1. The occasion referred to. I was dumb, etc. We are not told what the particular trial was, that each one may apply it to his own affliction, and because all are to be viewed in the same light.

2. The conduct of the psalmist upon that particular occasion: I opened not my mouth. (a) Not in anger and rebellion against God in murmurs or complaints. (b) Not in impatience, or complaining, or angry feelings against men. (c) The reason he assigns for this conduct: Because thou didst it. G. Rogers.
