Isaiah 16:4-5

4, 5. Be thou a covert Who the object of address here is, is matter of dispute. Some make it Moab, others, Judah. The sense depends on which it is. If it be Moab, as the older and later but best accredited writers hold, the “outcasts” here are those of Israel; if it be Israel, those of Moab. The exhortation may be appropriate either way. Give the fugitives, whoever they are, shelter; they will not need it long. The extortioner will soon cease. Oppression will soon be over. Trampling invaders, whether here or there, will in judgment be consumed. Not unlikely the reference is to invading Assyrians. Possibly, also, a comprehensive extension is made to oppressors, at one time of Judah, at another of Moab, covering the whole history of both. The transition from the one to the other, if it exist, is sudden and obscure: yet as an appeal it might well enough apply to both. Applying to the Jews as affording shelter to fugitives from Moab, the promise is that their own government shall be strengthened by this exercise of mercy, and their prosperity promoted by the coming of a king in the family of David the Messianic king who shall judge and seek justice and be prompt in equity and truth. And this means not Hezekiah merely, but all good kings to come, but chiefly the high antitype of David, the Messiah.
