Acts 2:23 → Psalms 2:7

Peter's claim that Jesus was "delivered up by God's set plan (tē hōrismenē boulē) and foreknowledge" frames the crucifixion as the execution of a divine decree. Behind this language Allen (1970–1971) traced the influence of the royal decree (ḥōq) of Psalm 2:7 — "I will proclaim the decree spoken to Me by the LORD" — arguing that the NT's (pro)horizein ("determine, decree") vocabulary for God's fixed plan concerning Jesus is shaped by the psalm's installation-decree. On this reading, the substructure of Acts 2:23 is Davidic sonship: the cross is not the interruption of the Son's installation but a stage within the decreed program that runs from the conspiracy of Psalm 2:1-2 — cited explicitly at Acts 4:25-28, where the same vocabulary recurs ("whatever Your hand and Your plan had decided beforehand [proōrisen]") — to the enthronement-"today" of Psalm 2:7 (Acts 13:33). The allusion is lexical rather than quotational; its strength is Allen's decree-argument together with the recurrence of Psalm 2 throughout the same Petrine preaching context (2:31, 34-36; 4:25-26), and it should not be pressed beyond allusion-grade. But it coheres precisely with Luke's larger theology of the passion: the lawless act of the rulers was itself enclosed within the boulē of the God who had already decreed His Son's kingship — the rage of the nations accomplishing the very installation it sought to prevent.
