Isaiah 52:7-12 English Standard Version (ESV)
7 How beautiful upon the mountains
are the feet of him who brings good news,
who publishes peace, who brings good news of happiness,
who publishes salvation,
who says to Zion, “Your God reigns.”
8 The voice of your watchmen—they lift up their voice;
together they sing for joy;
for eye to eye they see
the return of the Lord to Zion.
9 Break forth together into singing,
you waste places of Jerusalem,
for the Lord has comforted his people;
he has redeemed Jerusalem.
10 The Lord has bared his holy arm
before the eyes of all the nations,
and all the ends of the earth shall see
the salvation of our God.

11 Depart, depart, go out from there;
touch no unclean thing;
go out from the midst of her; purify yourselves,
you who bear the vessels of the Lord.
12 For you shall not go out in haste,
and you shall not go in flight,
for the Lord will go before you,
and the God of Israel will be your rear guard.

Romans 10:13-17 English Standard Version (ESV)

13 For “everyone who calls on the name of the Lord will be saved.”

14 How then will they call on him in whom they have not believed? And how are they to believe in him of whom they have never heard?[a] And how are they to hear without someone preaching? 15 And how are they to preach unless they are sent? As it is written, “How beautiful are the feet of those who preach the good news!” 16 But they have not all obeyed the gospel. For Isaiah says, “Lord, who has believed what he has heard from us?” 17 So faith comes from hearing, and hearing through the word of Christ.
