And they took their journey from Elim, and all the congregation of the children of Israel came unto the wilderness of Sin, which is between Elim and Sinai, on the fifteenth day of the second month after their departing out of the land of Egypt. The wilderness of Sin - This desert lies between Elim and Sinai, and from Elim, Dr. Shaw says, Mount Sinai can be seen distinctly. Mr. Ainsworth supposes that this wilderness had its name from a strong city of Egypt called Sin, near which it lay. See Ezekiel 30:15, Ezekiel 30:16. Before they came to the wilderness of Sin, they had a previous encampment by the Red Sea after they left Elim, of which Moses makes distinct mention Numbers 33:10, Numbers 33:11.
The fifteenth day of the second month - This was afterwards called Ijar, and they had now left Egypt one month, during which It is probable they lived on the provisions they brought with them from Rameses, though it is possible they might have had a supply from the seacoast. Concerning Mount Sinai, See Clarke's note on Exodus 19:1.
