John Trapp on Zechariah 14:16

Verſe 16. Every one that is left of all the nations] i.e. that hath eſcaped the plague, verſe 12. and is beaten into a better mind: as thoſe Hunnes, that, vanquiſhed by the Chriſtians, concluded that Chriſt was the true God, and became his ſubjects. God had promiſed before to ſubvert the Churches enemies, but here to convert them, which is farre better. And it ſhall appear to be ſo (as converſion cannot be hid; you cannot turn a bell, but it will make a ſound: and report its own motion. See Gal. 1.23.)

for they ſhall even go up] ſc. to the Temple, which ſtood upon mount Moriah:

to worſhip the king the Lord of Hoſts].Eſay 16.1[illegible: 1 letter] to ſend a lamb (or an homage peny) to the Lord of the whole earth.

and to keep the feaſt of Tabernacles] In a due manner, which had not been rightly done (a marvellous thing) all along during the reigne of David, Solomon, and all thoſe ſucceeding Reformers, till about theſe times; as appears Neb. 8.16, 17, 19. The ſence of this text is, that the converted Gentiles ſhall joyn with the Jews, in the ſincere ſervice of God according to his will, and not according to their own brains and fancies: that they ſhall worſhip him with the ſame rites, in the ſame places and aſſemblies which they do: that Jehovah may be one, and his name one amongſt them, as verſe 9. that there may be no more Jew, and Gentile, Barbarian or Scythian, bond or free, but Chriſt may be all, and in all.Col. 3.11 That thoſe two ſticks being joyned into one, Ezek. 37.16. all Iſrael may be ſaved, Rom. 11.26. and raiſed as from the dead, verſe 15. the Gentiles alſo may have their part in the ſame reſurrection. All this is here ſet forth in ſuch termes, and under ſuch types as were then moſt in requeſt: as of going up to the Temple, keeping the feaſt of Tabernacles, &c. All which expreſſions are parabolicall, ſymbolicall, and enigmaticall: framed to the capacity of the Jews, much addicted to theſe legall rites and ſhadows, then in uſe, but now done away, Col. 2.17. Heb. 10.1. whatever the Jews conclude from this text for their continuance under Meſſias his kingdome. Chriſtians have their feaſts or holy-dayes too, 1 Cor. 5.8. yea their feaſt of Tabernacles in a myſtieall ſence, 1 Pet. 2.11. Heb. 11.1, 9.
