Matthew Poole and continuators on Psalms 73:21

21 Thus my heart was grieved, and I was pricked in my reins .

So as I have above expressed; for this Particle so taken, doth not belong to what he had now wisely and piously said in the next foregoing Verses, but to what he had unadvisedly spoken in the former Verses, as is Evident from the following Verse. Or, Nevertheless, as this Particle is oft used. Although I knew very well that the Prosperity of sinners would have a sudden and Dismal end, yet I was so foolish as to be grieved at it.

I was heartily and deeply wounded with disquieting Thoughts, and tormenting Passions, Envy and Sorrow, and Anger.
