Isaiah 52

How beautiful on the mountains
are the feet of those who bring good news
of peace and salvation,
the news that the God of Israel reigns!
(verse 7)

Beautiful are the feet of those who bring good news ...
Good news = news of peace + salvation = news that God reigns!

The Lord will demonstrate his holy power
before the eyes of all the nations.
The ends of the earth will see
the salvation of our God.
Go now, leave your bonds and slavery.
Put Babylon behind you,
with everything it represents,
for it is unclean to you.
You are the Lord's holy people.
Purify yourselves,
you who carry home the vessels of the Lord.
You will not leave in a hurry,
running for your lives.
For the Lord will go ahead of you,
and the God of Israel will protect you from behind.
(verses 10-12)

What do 'the vessels of the Lord' represent?

All the nations will see the Lord demonstrate His holy power ...
The ends of the earth will see the salvation of our God ...
Go now, leave our bonds and slavery. Put Babylon behind us, with everything it represents, for it is unclean to us. We are the Lord's holy people. Purify ourselves, we who carry home the vessels of the Lord. The Lord will go ahead of us, and protect us from behind.

See, my servant will prosper;
he will be highly exalted.
Many were amazed when they saw him—
beaten and bloodied,
so disfigured one would scarcely know he was a person.
And he will again startle* many nations.
Kings will stand speechless in his presence.
For they will see what they had not been told;
they will understand what they had not heard about.
(verses 13-15)
