Leviticus 11:21-23

Four kinds of these swarming things which may be eaten are mentioned. The first and last of these occur frequently in the O.T., the second and third only here.

The first is "arbeh, the general term for a locust, and from the passages in which it occurs (e.g. Exodus 10:4, of the plague of locusts, Judges 6:5; Judges 7:12, of invading troops) is clearly a highly destructive insect.

The fourth, ḥâgâb, is translated -grasshopper" except in 2 Chronicles 7:13, where both R.V. and A.V. render -locust." From the words which follow, -to devour the land," it is clear the grasshopper is not meant, but one of the locust family. The rendering -beetle" of A.V. for the third is certainly wrong. The Heb. word probably means a galloper, and the characteristic of the four kinds is that they -have legs … to leap withal."

That they were actually eaten appears from Matthew 3:4; Mark 1:6.
