In my last post, we learned about The New Heavens and A New Earth in Yesha’yahu 65:17-25. In this post, we learn about The Humble and Contrite Spirit in Yesha’yahu 66:1-6.
1 “Heaven is My throne,” says Adonai, “and the earth is My footstool. What kind of house could you build for Me? What sort of place could you devise for My rest?
One of the presumptions of the pre-exilic people of Adonai was that the Temple was the place where Adonai lived. This attitude had no justification, especially considering the speech King Solomon gave when he dedicated the Temple (1Kings 8:27). Thus, Adonai began the final prophesy in the book of Yesha’yahu by reminding His people that His presence fills heaven (My throne) and earth (My footstool).
The house spoken of here refers to the Temple. Before the Tribulation, Antichrist will work out a compromise between the Muslims and the Jews, allowing the Temple to be rebuilt on the Temple Mount. This will give him even greater power in the geopolitical, political arena.
2 Didn’t I Myself make all these things? This is how they all came to be,” says Adonai. “The kind of person on whom I look with favor is one with a poor and humble spirit, who trembles at My Word.
Adonai made everything. This means that people should honor and fear Adonai, which will result in humility, submissiveness to Adonai, and total obedience to His commands.
3 Those others might as well kill a person as an ox, as well break a dog’s neck as sacrifice a lamb, as well offer pig’s blood as offer a grain offering, as well bless an idol as burn incense. Just as these have chosen their ways and enjoy their disgusting practices,
The dog was not a sacrificial animal in Isra’el, although it was used in this manner in Hittite Anatolia. Pigs and dogs figured prominently in the rituals of the Hittites in Anatolia in the Late Bronze Age. When confronted with a ritual impurity, the Hittites often slaughtered a pig (usually by cutting it in half). Pigs and dogs were particularly prominent in worship of chthonic deities (those having to do with the netherworld. Some have suggested that the treatment of the pig in this type of ritual may have been one reason why the pig was considered unclean. 
Here, the Lord says, “I’m not impressed by your structures or your sacrifices. After all, you can’t offer Me anything I don’t already own. What I want is for you to humble yourselves before Me and be obedient to Me.”
4 so I will enjoy making fools of them, and bring on them the very things they fear. For when I called, no one answered; when I spoke, they did not hear. Instead, they did what was evil in My sight and chose what did not please Me.”
Adonai would choose also; He would choose their punishment.
5 Hear the word of Adonai, you who tremble at His Word: “Your brothers, who hate you and reject you because of My name, have said: ‘Let Adonai be glorified, so we can see your joy.’ But they will be put to shame.” 6 That uproar in the city, that sound from the Temple, is the sound of Adonai repaying His foes what they deserve. ~ Isaiah 66:1-6 (CJB)
Trembling at Adonai’s Word indicates the kind of submission to Adonai that leads to obedience. The brothers (fellow Israelites) mocked the faithful by saying, let Adonai be glorified because they did not think that would happen. Adonai will see that the mockers get what they deserve.
There will come a time when the grace of Adonai will end, and those who reject Him will be confirmed in their choices. With Adonai repaying His foes what they deserve, no one will stand, no one will escape.
In my next post, we continue to examine the last chapter in the prophecy of Yesha’yahu, learning about Rejoice with Yerushalayim in Yesha’yahu 66:7-14.
 Bible Background Commentary – Old Testament. As I have stated in the past, there is no passage in Scripture that specifically explains why God considered pigs as unclean and therefore not to be eaten.
