A voice cries out: "In the wilderness prepare the way of the Lord, make straight in the desert a highway for our God.

Get you up to a high mountain, O Zion, herald of good tidings; lift up your voice with strength, O Jerusalem, herald of good tidings, lift it up, do not fear; say to the cities of Judah, "Here is your God!"
