Take it, and eat it up: thus Ezekiel was bidden to eat the roll; and it was in his mouth as sweet as honey, Ezekiel 2:8, Ezekiel 3:3. The eating of a book signifies the due reading of it, digesting it, and meditating upon the matters in it. And it shall make thy belly bitter, but it shall be in thy mouth sweet as honey; it should be sweet in his month, as it was the revelation of the mind and will of God, (which is sweet to all pious souls; see Jeremiah 15:16), but in his belly it should be bitter, being the revelation of the Divine will, as to the bringing such terrible judgments upon an impenitent people.
