Matthew Poole and continuators on Psalms 102:9

9 For I have eaten ashes like bread , and mingled my drink with weeping .

So this Verse gives a reason either of his great sadness expressed v. 6, 7. or why they swore by him in the sence last given. Or, Surely, as this Particle is oft used. Or, Therefore, because of those bitter reproaches last mentioned.

The sence is, Dust and ashes are as constant and familiar to me as the eating of my Bread, I cover my head with them, I sit, yea lye down and roll my self in them, as Mourners oft did, 2 Sam. 13. 19. Iob 2. 8, 12. and 16. 15. Isai. 47. 1. Mich. 1. 10. by which means the ashes might easily be mingled with their meat, as tears were with their drink in the next Clause.

He alludes to the custom of mingling their Wine with Water.
