Charles Spurgeon Commentary Jeremiah 14:19

"Hast thou utterly rejected Judah? hath thy soul loathed Zion? why hast thou smitten us, and there is no healing for us? We looked for peace, but no good came; and for a time of healing, and, behold, dismay!" — Jeremiah 14:19 (ASV)

That is not exactly praying, but it is very like it. Jeremiah is asking the Lord whether he can really have cast off his people.
