sharpen

But all the Israelites went down to the Philistines, to sharpen every man his share, and his coulter, and his axe, and his mattock.

Yet they had a file for the mattocks, and for the coulters, and for the forks, and for the axes, and to sharpen the goads.

His severe wrath shall he sharpen for a sword, and the world shall fight with him against the unwise.
