Adam Clarke on Ezekiel 3:3

It was in my mouth as honey - It was joyous to me to receive the Divine message, to be thus let into the secrets of the Divine counsel, and I promised myself much comfort in that intimate acquaintance with which I was favored by the Supreme Being. In Rev 10:10 we find St. John receiving a little book, which he ate, and found it sweet as honey in his mouth, but after he had eaten it, it made his belly bitter, signifying that a deep consideration of the awful matter contained in God's word against sinners, which multitudes of them will turn to their endless confusion, must deeply afflict those who know any thing of the worth of an immortal spirit.
