Matthew Poole and continuators on Acts 26:22

22 Having therefore obtained help of God, I continue unto this day, witnessing both to small and great, saying none other things than those which the prophets and Moses did say should come:

That Paul continued till then alive, notwithstanding all the fraud and force of his enemies, is acknowledged by him to be from God; from whence he inferrs towards his justification, that what he had done was but in a becoming gratitude towards that God who had maintained him in life unto that very day.

Witnessing to all sorts, Princes, or people; implying, that the truths of the Gospel, and the things of God, concerned Agrippa as well as the meanest of his Auditors; and indeed with God there is no respect of persons, and that we are all one in Christ Jesus, Gal. 3.28.

Moses was himself also a Prophet, but he is here made especially mention of, because of his excellency above the other Prophets (unto whom God spake face to face) as also because he was the Law-giver to the Iews, and whom, upon all occasions they pretended to yield obedience to.
