Paragraphs help with understanding. Here's how the scripture reads.
9 "When you go out as an army against your enemies, you shall keep yourself from every evil thing.
10 "If there is among you any man who is unclean because of a nocturnal emission, then he must go outside the camp; he may not reenter the camp. 11 "But it shall be when evening approaches, he shall bathe himself with water, and at sundown he may reenter the camp.
12 "You shall also have a place outside the camp and go out there, 13 and you shall have a spade among your tools, and it shall be when you sit down outside, you shall dig with it and shall turn to cover up your excrement. 14 "Since the Lord your God walks in the midst of your camp to deliver you and to defeat your enemies before you, therefore your camp must be holy; and He must not see anything indecent among you or He will turn away from you.
vs 10 and 11 are one paragraph dealing with one subject matter. While vs 12-14 are another paragraph dealing with another subject matter.
13 "But go and learn what this means: ' I DESIRE COMPASSION,AND NOT SACRIFICE,' for I did not come to call the righteous, but sinners."
