Weeds, like habits, are best tended to when they are small. By the time you can easily see them they will have put out deep roots and require vigorous effort. A plain hoe you buy from the garden store will not suffice until you put an edge on it with a file. You will also tend to favor one side. Put an edge there as well. In this manner it becomes your hoe, fit to your hand and a mighty instrument of war in the service of your Lord.
