Adam Clarke on Numbers 10:12

The cloud rested in the wilderness of Paran - This was three days' journey from the wilderness of Sinai, (see Num 10:33), and the people had three stations; the first at Kibroth-hattaavah, the second at Hazeroth, Num 11:35, and the third in the wilderness of Paran, see Num 12:16. But it is extremely difficult to determine these journeyings with any degree of exactness; and we are often at a loss to know whether the place in question was in a direct or retrograde position from the place previously mentioned.
