Isaiah 2: 11-12. “The lofty looks of man shall be humbled, and the haughtiness of men shall be bowed down, and the Lord alone shall be exalted in that day. For the day of the Lord of hosts shall be upon every one that is proud and lofty, and upon every one that is lifted up; and he shall be brought low.”
When mankind tried to build a tower to heaven to reach God on his own terms,exalting himself above God, God destroyed the tower, confounded the language, and put them all to shame (Gen. 11:1-9).
Man is still trying to exalt himself above God, and for Judah, there would be sure and soon-coming judgment for their failure to submit to His authority. Those who were proud and haughty in their own importance would soon be brought low, and God alone would be exalted.
Verse 12 mentions the “day of the Lord of Hosts.” This is a switch from the impending doom on Judah and a change into the far future, when the rule of mankind, especially the Gentiles, would come to an end. This is not speaking of a 24-hour day, but of a period of time when God will take control. From this point to the end of this chapter, we read of the judgments that will fall on all the nations when Jesus comes to rule and reign on earth for 1,000 years.
That period is described as “the day of the Lord.” This present period is called “man’s day” (I Cor. 4:3) where the phrase is “man’s judgment,” for in our day we are inundated with the ungodly and unbiblical judgment of men on so many things. There have been days of the Lord in His dealings with Israel in the past, but this usage indicates a far future period, as in Joel 2:31 and Malachi 4:5. There will be a complete overthrow of Gentile power (Isa. 13:9-11, 34; Dan. 2:34,44; Obad. 15) and the deliverance of the Jews from the centuries of persecution since the crucifixion of Jesus Christ.
