Then the LORD told me, "Don't pray for the welfare of these people.
"Who will have pity on you, Jerusalem, and who will grieve for you? Who will go out of his way to ask about your welfare?
Seek the welfare of the city to which I've exiled you and pray to the LORD for it, for your welfare depends on its welfare.'
No one should seek his own welfare, but rather his neighbor's.
