A promise to all people

Isa. 25:6-9 was the Old Testament reading this morning at our Easter service (emphasis added):

6 On this mountain the Lord of hosts will make for ALL PEOPLES
a feast of rich food, a feast of well-aged wine,
of rich food full of marrow, of aged wine well refined.
7 And he will swallow up on this mountain
the covering that is cast over ALL PEOPLES,
the veil that is spread over ALL NATIONS.
8 He will swallow up death forever;
and the Lord God will wipe away tears from ALL FACES,
and the reproach of his people he will take away from ALL THE EARTH,
for the Lord has spoken.
9 It will be said on that day,
“Behold, this is our God; we have waited for him, that he might save us.
This is the Lord; we have waited for him;
let us be glad and rejoice in his salvation.”
