ח He said to him, "Why were gnats created? For they only exist in the world for just one day, and then they are destroyed and others are created?" He said to him, "On the merit of one gnat who will in the future get revenge on the evil Titus. And the remainder- to give life to raven chicks when they hatch from the eggs. They go out to their nest and their parents flee and leave them, and they cry out to them, as it says, (Psalms 147:9) 'to the raven's brood what they cry for' and they bring them gnats in their mouth, and they eat it and live off of it for three days. After three days they turn black and their parents return to them, and the Holy Blessed One prepares the cure before the harm."
