Acts 11:30
This they did, sending their gift to the elders by Barnabas and Saul.—the practical action (sending relief) is mediated through Barnabas and Saul, establishing their official standing as delegated representatives. The 'elders' (presbyteroi, the Jerusalem church's leadership structure) receive the gift. The relief act (apostolē, 'sending' of aid) becomes a paradigm of koinōnia (fellowship/mutual aid) across the early church and establishes Saul/Paul's later role in the Jerusalem collection.
