cha.gav denotes a locust, both as an insect in concrete settings and as a comparison for small-looking people.

The term most often denotes the insect in concrete settings: it may eat the land, drag itself along, or be named among creatures that may be eaten. In plural comparisons, inhabitants or scouts are portrayed as like locusts.

1. The insect in concrete settings · dominant

   The singular noun occurs in clauses about an insect's activity or classification: in 2 Chronicles 7:13 the APB renders a commanded locust that will “eat the land”; in Ecclesiastes 12:5 it renders the locust as dragging itself along; and in Leviticus 11:22 it appears among creatures that may be eaten according to their kinds.

2. A comparison for human smallness · common

   The plural noun is used in comparisons involving people. In Isaiah 40:22 the APB renders earth's inhabitants as “like locusts,” while in Numbers 13:33 the speakers describe themselves as “like grasshoppers” in their own sight and in the sight of others.

   Isaiah 40:22Numbers 13:33

In the Anselm Project Bible: The APB usually uses “locust,” including the land-eating and crawling clauses, but uses “grasshoppers” in Numbers 13:33. These English choices show the verse-level presentation rather than separate lexical definitions.
