Charles Spurgeon Commentary Isaiah 48:2

"(for they call themselves of the holy city, and stay themselves upon the God of Israel; Jehovah of hosts is his name):" — Isaiah 48:2 (ASV)

They profess to trust him, but they do not love him; they call themselves of the holy city, but they certainly are not holy citizens.

Alas, that God should have to speak to men upon such a matter as this! It is self-evidently wicked, but they will not see it.
