God starts Moses on a military campaign to conquer the Promised Land on the east side of Jordan. This campaign begins sometime around the middle of the sixth month. This is established through the following scriptures: “Now when all the congregation saw that Aaron was dead, all the house of Israel mourned for Aaron thirty days” (Num. 20:29). “And Aaron the priest went up into Mount Hor at the commandment of the LORD, and died there, in the fortieth year after the children of Israel were come out of the land of Egypt, in the first day of the fifth month” (Num. 33:38).

Aaron died at the beginning of the fifth month and was mourned 30 days. Thus they started their journey to the Promised Land at the beginning of the sixth month. Deuteronomy 1:2 shows eleven days were required to arrive at Mt. Horeb. Numbers 33:41-49 records the Israelites had a total of eight campsites during these eleven days. The forth campsite after leaving Mt. Hor puts them on the border between Moab and the Amorites, placing them at the border of the Promised Land. This sets the travel time at about half of the eleven days.
