There are ten Hebrew words used in Scripture to signify locust. In the New Testament locusts are mentioned as forming part of the food of John the Baptist (Matt. 3:4; Mark 1:6). By the Mosaic law they were reckoned "clean," so that he could lawfully eat them. The name also occurs in Rev. 9:3, 7, in allusion to this Oriental devastating insect. Locusts belong to the class of Orthoptera, i.e., straight-winged. They are of many species. The ordinary Syrian locust resembles the grasshopper, but is larger and more destructive. "The legs and thighs of these insects are so powerful that they can leap to a height of two hundred times the length of their bodies. When so raised they spread their wings and fly so close together as to appear like one compact moving mass." Locusts are prepared as food in various ways. Sometimes they are pounded, and then mixed with flour and water, and baked into cakes; "sometimes boiled, roasted, or stewed in butter, and then eaten." They were eaten in a preserved state by the ancient Assyrians. The devastations they make in Eastern lands are often very appalling. The invasions of locusts are the heaviest calamites that can befall a country. "Their numbers exceed computation: the hebrews called them the countless,' and the Arabs knew them as the darkeners of the sun.' Unable to guide their own flight, though capable of crossing large spaces, they are at the mercy of the wind, which bears them as blind instruments of Providence to the doomed region given over to them for the time. Innumerable as the drops of water or the sands of the seashore, their flight obscures the sun and casts a thick shadow on the earth (Ex. 10:15; Judg. 6:5; 7:12; Jer. 46:23; Joel 2:10). It seems indeed as if a great aerial mountain, many miles in breadth, were advancing with a slow, unresting progress. Woe to the countries beneath them if the wind fall and let them alight! They descend unnumbered as flakes of snow and hide the ground. It may be like the garden of Eden before them, but behind them is a desolate wilderness. At their approach the people are in anguish; all faces lose their colour' (Joel 2:6). No walls can stop them; no ditches arrest them; fires kindled in their path are forthwith extinguished by the myriads of their dead, and the countless armies march on (Joel 2:8, 9). If a door or a window be open, they enter and destroy everything of wood in the house. Every terrace, court, and inner chamber is filled with them in a moment. Such an awful visitation swept over Egypt (Ex. 10:1-19), consuming before it every green thing, and stripping the trees, till the land was bared of all signs of vegetation. A strong north-west wind from the Mediterranean swept the locusts into the Red Sea.", Geikie's Hours, etc., ii., 149. a well-known insect, of the grasshopper family, which commits terrible ravages on vegetation in the countries which it visits. "The common brown locust is about three inches in length, and the general form is that of a grasshopper." The most destructive of the locust tribe that occur in the Bible lands are the (Edipoda migratoria and the Acridium peregrinum ; and as both these species occur in Syria and Arabia, etc., it is most probable that one or other is denoted in those passages which speak of the dreadful devastations committed by these insects. Locusts occur in great numbers, and sometimes obscure the sun. (Exodus 10:15; Judges 6:5; Jeremiah 46:23) Their voracity is alluded to in (Exodus 10:12,15; Joel 1:4,7) They make a fearful noise in their flight. (Joel 2:5; Revelation 9:9) Their irresistible progress is referred to in (Joel 2:8,9) They enter dwellings, and devour even the woodwork of houses. (Exodus 10:6; Joel 2:9,10) They do not fly in the night. (Nahum 3:17) The sea destroys the greater number. (Exodus 10:19; Joel 2:20) The flight of locusts is thus described by M. Olivier (Voyage dans l' Empire Othoman, ii. 424): "With the burning south winds (of Syria) there come from the interior of Arabia and from the most southern parts of Persia clouds of locusts (Acridium peregrinum), whose ravages to these countries are as grievous and nearly as sudden as those of the heaviest hail in Europe. We witnessed them twice. It is difficult to express the effect produced on us by the sight of the whole atmosphere filled on all sides and to a great height by an innumerable quantity of these insects, whose flight was slow and uniform, and whose noise resembled that of rain: the sky was darkened, and the light of the sun considerably weakened. In a moment the terraces of the houses, the streets, and all the fields were covered by these insects, and in two days they had nearly devoured all the leaves of the plants. Happily they lived but a short time, and seemed to have migrated only to reproduce themselves and die; in fact, nearly all those we saw the next day had paired, and the day following the fields were covered with their dead bodies." "Locusts have been used as food from the earliest times. Herodotus speaks of a Libyan nation who dried their locusts in the sun and ate them with milk. The more common method, however, was to pull off the legs and wings and roast them in an iron dish. Then they thrown into a bag, and eaten like parched corn, each one taking a handful when he chose."--Biblical Treasury. Sometimes the insects are ground and pounded, and then mixed with flour and water and made into cakes, or they are salted and then eaten; sometimes smoked; sometimes boiled or roasted; again, stewed, or fried in butter.
