The Trinity in the Old Testament

In Acts, chapter 28 in the New Testament. Can you please read verses 25 through 27? And we give them reading? Yes. Make the heart of this people unreceptive, make their ears unresponsive and paste their eyes together so that they may not see with their eyes and hear and hear with their earsSo that their heart may not understand and they may not turn back and be healed. So let's see if some of that comes to fruition in the Jehovah's Witnesses actual Bible. When might I add the spirit filled men of God when they were spreading the gospel did not have the New Testament?"
