plow

Definition:

A "plow" is a farm tool that is used for breaking up soil to prepare a field for planting.

Plows have sharp, pointed prongs that dig into the soil. They usually have handles that the farmer uses to guide the plow.
In Bible times, plows were usually pulled by a pair of oxen or other work animals.
Most plows were made of hard wood, except for the sharp points which were made of a metal, such as bronze or iron.
