Psalms 102:9

(9) Ashes like bread.—Lamentations 3:16. A figurative expression, like “dust shall be the serpent’s meat” (Isaiah 65:25; comp. Genesis 3:14). With the last clause comp. Psalms 42:3, “tears have been my meat day and night.” So too, as an emblem of disappointment, a modern poet:—

“But even while I drank the brook, and ateThe goodly apples, all these things at onceFell into dust, and I was left alone.”TENNYSON: Holy Grail.
