Isaiah 16:1

(Chapter XVI—Verse 1) Send forth the lamb, the ruler of the earth, from the rock of the desert, to the mountain of the daughter of Zion. And it shall be like a flying bird, and the chicks flying from the nest. So shall the daughters of Moab be in the crossing of the Arnon. Plan a counsel, gather a counsel, place your shadow like the night at midday. Hide the fugitives, and do not betray the wanderers. My outcasts shall dwell with you, Moab shall be their shelter from the face of the devastator. For the dust is ended, the wretched one is consumed, the one who trampled the earth has ceased. And a throne will be established in mercy: and he will sit upon it in truth in the tabernacle of David: judging and seeking judgment; and quickly rendering what is just. This is what we have interpreted from the Hebrew: send forth the lamb, the ruler of the earth, it can be read as follows: send forth the lamb to the ruler of the earth, in which case the lamb himself is not the ruler of the earth, as we have interpreted according to the history, but the lamb is to be sacrificed to the ruler of the earth. Therefore, this lamb, who either is the ruler of the earth or is sacrificed to the ruler of the earth, is from the nation of the Moabites, and from those who fled from Moab, and deserve to have the Prince be a lion. But Ruth, from whom Christ is born (Matt. 1:5), signifies the rock of the desert, because according to God's command, the Moabites and Ammonites do not enter the Church of God until the tenth generation, and not forever (Deut. 1). But whoever flees from the desert of Moab, so that we may return from prophecy to anagoge, and having disregarded falsehood, stands on the mountain of truth, will be like a flying bird; and like young birds flying from the nest, lest they be devoured by Moabite serpents.

(Chapter 16, Verse 1) Send forth the Lamb, the ruler of the earth, from the desert rock to the mountain of the daughter of Zion. This, we interpret, is not history, but prophecy. However, every prophecy is wrapped in riddles and, with interrupted sentences, while speaking of one thing, goes on to another: lest if it preserves the order of Scripture, it be not a prophecy, but a narrative.

Here he describes the condition of their punishment, and he sets out two conditions: first, equity on the part of the one who judges; second, deception on the part of the one who suffers the punishment: and it shall come to pass, when it is …

"Now you would be glad to send a lamb to Mount Zion, to make the God of Israel your friend; but it is too late: the decree has gone forth, the consumption is determined, and the daughters of Moab shall be cast out as a wandering bird, "

Send ye the lamb - Lowth renders this, ‘I will send forth the son from the ruler of the land;’ meaning, as he supposes, that under the Assyrian invasion, even the young prince of Moab would be obliged to flee for his life through the desert, that he might escape to Judea; and “that” thus God says that “he” would send him.
