Matthew Henry on Revelation 10:8-11

Most men feel pleasure in looking into future events, and all good men like to receive a word from God. But when this book of prophecy was thoroughly digested by the apostle, the contents would be bitter; there were things so awful and terrible, such grievous persecutions of the people of God, such desolations in the earth, that the foresight and foreknowledge of them would be painful to his mind. Let us seek to be taught by Christ, and to obey his orders; daily meditating on his word, that it may nourish our souls; and then declaring it according to our several stations. The sweetness of such contemplations will often be mingled with bitterness, while we compare the Scriptures with the state of the world and the church, or even with that of our own hearts.
