Adam Clarke on Isaiah 30:6

The burden - משא massa seems here to be taken in its proper sense; the load, not the oracle. The same subject is continued; and there seems to be no place here for a new title to a distinct prophecy.

Does not burden of the beasts of the South in this place relate to the presents sent by Hoshea king of Israel to the South - to Egypt, which lay south of Judea, to engage the Egyptians to succor him against the king of Assyria?

Into the land of trouble and anguish "Through a land of distress and difficulty" - The same deserts are here spoken of which the Israelites passed through when they came out of Egypt, which Moses describes, Deu 8:15, as "that great and terrible wilderness wherein were fiery serpents, and scorpions, and drought; where there was no water. "And which was designed to be a kind of barrier between them and Egypt, of which the Lord had said, "Ye shall henceforth return no more that way," Deu 17:16.

Shall not profit them - A MS. adds in the margin the word למו lamo, them, which seems to have been lost out of the text: it is authorized by the Septuagint and Vulgate.
