Thy sons have fainted, they lie; rather, thy sons fainted; they lay. The prophet describes the siege and capture of Jerusalem as past, because his standpoint is the time of the Captivity. He depicts tile inhabitants of Jerusalem as "faint" through famine, and so weak that they lie prostrate about the streets.
As a wild bull in a net; rather, like a gazelle in a net—panting, exhausted, incapable of the hast resistance. They are full of the fury of the Lord; i.e. the fury of the Lord has been fully poured out upon them.
