Charles Ellicott Commentary Deuteronomy 2:7

"For Jehovah thy God hath blessed thee in all the work of thy hand; he hath known thy walking through this great wilderness: these forty years Jehovah thy God hath been with thee; thou hast lacked nothing." — Deuteronomy 2:7 (ASV)

The Lord thy God hath blessed thee. —There is nothing unreasonable in the view suggested by these words, that the Israelites acquired wealth by trade or by ordinary occupations during their wilderness journey. They had skilled workmen among them.
