2 you who call yourselves citizens of the holy city and claim to rely on the God of Israel— the LORD Almighty is his name:

Read Isaiah 48:2 Using Other Translations

For they call themselves of the holy city, and stay themselves upon the God of Israel; The LORD of hosts is his name.
For they call themselves after the holy city, and stay themselves on the God of Israel; the LORD of hosts is his name.
even though you call yourself the holy city and talk about depending on the God of Israel, whose name is the LORD of Heaven’s Armies.
