The Talmudical commentators wrote rather copiously about the Pearl, respecting the nature of which they were somewhat perplexed, as it was a gem and yet not a mineral. They thought that it lay at the bottom of the sea, under flat, slab-like stones some of which had Pearls beneath them, but the greater part were without them. In consequence of the difficulty of diving and the precariousness of the search, a number of proverbs were current. For example, a person who persevered in some fruitless search was said to be a diver who brought up stones without Pearls. If one person laboured and another took the credit, it was said that the one would not have found the Pearl if the other had not brought up the stone.
In consequence of the labour and research required for seeking wisdom, it was proverbially likened to a Pearl, and in this sense we must understand the warning of our Lord, not to cast Pearls before swine. The "pearl of great price" is another form of the same metaphor.
This metaphor holds good in almost all Oriental languages.
There is also a proverb which bears a curious resemblance to the well-known "painting the lily and gilding refined gold:" "Whoso praises a priceless pearl undervalues it."
INSECTS.
Insects—Beetles not mentioned in Scripture—The Locust—Various species of the insect, and different words used to signify it—The Arbeh of Scripture, and its derivation—The two migratory Locusts at rest and on the wing—The Locust swarms—Gordon Cumming's account—Progress of the insect hosts—Vain attempts to check them—Tossed up and down as a Locust—Effect of the winds on the insect—The east and the west winds—Locusts used for food—Ancient and modern travellers—The food of St. John.
Considering the vast variety of insects which are found in Egypt, Syria, and Palestine, it is somewhat remarkable that so few should be mentioned by name. Not one single coleopteran is mentioned; for, although the Hebrew word chargol, which occurs in Lev. xi. 21, 22, is rendered in the Authorized Version as "beetle," the context shows that it could not have been a coleopterous insect at all, but must have belonged to the locusts. We will therefore pass to the insect next in order.
THE LOCUST.
Of the Locusts there are several species in Palestine, two of which are represented in the accompanying plate. Those on the ground are the common Migratory Locusts (Œdipoda migratoria), while those on the wing, which have long heads, are a species of Truxalis.
