The compassion of the prophet is here exposed. First is the exterior lamentation: "My eyes will flow without ceasing, without respite." Namely, crying: "without ceasing": from tears: "without respite": from tribulation for the people. For Jeremiah 9:18-19 asserts: "And our eyelids gush with water. For a sound of wailing is heard from Zion."
