Nehemiah 4:13

Therefore set I in the lower places behind the wall, [and] on the higher places, I even set the people after their families with their swords, their spears, and their bows.

Ver. 13. Therefore set I in the lower places] I took them off their work, and appointed them to stand upon their guard; appointing them their stations, and giving them orders.

I even set the people after their families] Or, according to their kindreds; for he knew that nature will move one kinsman to be truer to another in all dangers than a stranger; and that one kinsman will open his grief to his friend and take comfort at his hand, rather than to him whom he knoweth not. Hence Nehemiah in policy sorted his soldiers after this sort.

With their swords, their spears, and their bows] These were the ancient weapons of war; neither had death yet learned to cut his way through a wood of men out of the mouth of a murdering piece. Whether the Emperor Wenceslaus did well or ill in executing Barthold Swartz for inventing gunpowder, A. D. 1378, I determine not.
