Acts 7:16 belongs to Stephen's defense that rehearses Israel's history beginning with Abraham and tracing the generations of God's people. In that defense the history of the chosen people is presented as having a spiritual meaning made clear through Christ. It is part of his Old Testament testimony showing that the Scriptures and their history point to Christ. Christ's own voice spoke through the patriarchs and prophets whose history Stephen recounts.
