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."
There is then a final lamentation: "Until the Lord of heaven looks down and sees." Namely, with his eyes of divine mercy. Since Psalm 102:19 says: "That he looked down from his holy height, from heaven the Lord looked at the earth."
