The last three riddles which the Queen of Sheba put to Solomon were the following:
20. "What is this? A wooden well with iron buckets, which draw stones and pour out water." The king replied: "A rouge-tube."
21. "What is this? It comes as dust from the earth, its food is dust, it is poured out like water, and lights the house." "Naphtha."
22. "What is this? It walks ahead of all; it cries out loud and bitterly; its head is like the reed; it is the glory of the noble, the disgrace of the poor; the glory of the dead, the disgrace of the living; the delight of birds, the distress of fishes." He answered: "Flax."
