The word חסיל châsı̂yl - is supposed to denote a species of locust rather than the caterpillar. It literally means the devourer. In our version, however, it is uniformly rendered caterpillar as here; 1-Kings 8:37; 2-Chronicles 6:28; Isaiah 33:4; Joel 1:4; Joel 2:25. It occurs nowhere else.
And their labor unto the locust - The fruit of their labor; the harvests in their fields.
