'Six' in the Bible

All your men of war shall march around the city, going around the city once. You shall do this six days.

The second day they marched around the city once, and returned into the camp. They did this six days.

Maarath, Beth Anoth, and Eltekon; six cities with their villages.

Nibshan, the City of Salt, and En Gedi; six cities with their villages.
