1 Samuel 13:20
But all the Israelites went down to the Philistines, to sharpen every man his share, and his coulter, and his axe, and his mattock.
Isaiah 7:25
And on all hills that shall be digged with the mattock, there shall not come thither the fear of briers and thorns: but it shall be for the sending forth of oxen, and for the treading of lesser cattle.
