Is there anywhere in the bible where long dead people prayed on behalf of others?
The saints and angels in heaven offer the prayers of the saints on earth (recalling that "saint" was applied to Christ's faithful on earth as well
as those triumphant in heaven in the early Church). Revelations has particular instances where the prayers of these saints are offered by the saints
and angels in heaven to God in the form of incense. Now, one can supposse that those already triumphant, in God's presence, would have no need for
intercessory prayer, only those members of the Church Expectant (purgatory) and the Church Militant (on earth) would have cause to seek
intercession.
If you are interested there is a good, but not exhaustive, explanation of this to be found
here.
