And we are witnesses of all things which he did both in the land of the Jews, and in Jerusalem; whom they slew and hanged on a tree:

We may here admire how wonderfully Peter adapts his discourse to the capacity of his hearers. When speaking to the Jews, he proves Jesus to be their Messias, from the testimony of their prophets. On the present occasion, he only just alludes to the prophets, but confirms his discourse by the testimony of the miracles which Jesus had wrought in public, and were known to all the world. (Calmet)
