John Trapp on Isaiah 55:13

Ver. 13. Inſtead of the thorn ſhall come up the fir-tree] There ſhall be a bleſſed change of men and of manners: thoſe who before were ſtark naught or good for naught, yea vexatious and miſchievous, ſhall become fruitful and beneficial:Spinis paliurus acutis. Virg. Eclog. The Fir-tree is good for many uſes, the Myrtle brings berriers of excellent taſte, as Pliny tells us. The Chaldee thus paraphraſeth here, Juſt men ſhall riſe up inſtead of ſinners, and ſuch at fear the Lord in the room of the unrighteous. Sed cave ne hic ſomnies, ſaith Oecolampadius, but be warned you dream not as ſome do, that in this world and before the day of Judgement the wicked ſhall all be rooted out. For there will alwaies be Cains to perſecute Abels, &c.

And it ſhall be to the Lord for a name] i. e. For an honour: it ſhall be much for his glory, which is the end that he propoundeth to himſelf in all that he doth: and well he may; ſith 1. He is not in danger of doing any thing through vain-glory. 2. He hath none higher then himſelf, to whom to have reſpect.

For an everlaſting ſign] In monumentum non momentaneum, Heb. for a ſign of pepetuity or eternity.

That ſhall not be cut off] Or, that it (the Church) ſhall not be cut off.
