Isaiah 48:2

For; or, as others render it, and this particle frequently signifies, Though. And so this is added as a great aggravation of their want and neglect of truth and righteousness. They shall call themselves of the holy city: they glory in this, that they are citizens of Jerusalem, a city sanctified by God himself to be the only place of his true worship and gracious presence; which as it is a great privilege, so it laid a great obligation upon them to walk more holily than they did. Stay themselves; not by a true and well-grounded faith, but by a vain and presumptive confidence, flattering themselves, as that people commonly did, that they should enjoy peace and safety, notwithstanding all their wickedness, because they were the Lord's people, and had his temple and ordinances among them; which disposition the prophets frequently observe and sharply censure in them. The Lord of hosts is his name; or, whose name is the Lord of hosts.
