10 Go through, go through the gates; prepare ye the way of the people; cast up, cast up the highway; gather out the stones; lift up a standard for the people.
11 Behold, the Lord hath proclaimed unto the end of the world, Say ye to the daughter of Zion, Behold, thy salvation cometh; behold, His reward is with Him, and His work before Him.
12 And they shall call them, The holy people, The redeemed of the Lord: and thou shalt be called, Sought out, A city not forsaken.
In 40:3, a reference is made to the way prepared for the coming of the Messiah. Here, it is the way prepared for His people.
The highway mentioned here is a literal one referred to several times before this (v. 10; 11:10,19:23; 35:8).
The “standard” is always a rallying point around which the people can gather. Messiah, Himself will be the standard; the rallying point point of all nations. To Him they will come and to Him they will put their trust
Messiah is the salvation of all people in every corner of the earth. Not only His chosen people Israel, but also all the nations of the earth will enjoy the reward and blessing He has in store for them when they turn to Him in recognition and praise.
In that day, Israel will earn the name God’s holy people; and Jerusalem will enjoy the blessing and privilege of being a city everyone wants to see; of not forsaken.
Indeed, the world will be a far different place for everyone when Jesus rules and reigns in Jerusalem, and the whole world is blessed by His presence!
