Here is the sentence with correct capitalization: 

13 I set in the lower places behind the wall in exposed places, I even set the people, according to their families, with their swords, their spears and their bows.

I capitalized the first letter in the sentence, changing "i" to "I". It's important to start a sentence with a capital letter.
