"... Ezekiel, in conversation with a heavenly voice identified with the Lord God (compare Ezekiel 2:4), receives a κεφαλὶς βιβλίου which “a hand” (a circumlocution for the deity) spreads out before him. The prophet notices that the scroll is written on the front and the back, a description similar to that of the βιβλίον in Revelation 5:1 (ἔσωθεν καὶ ὄπισθεν).

Ezekiel 3:1–3 / Revelation 10:8–10 concern the handing over of a scroll and the directive to eat it. In Revelation 10:8, a “voice from heaven” (which had already addressed him in verse 4) orders the seer to approach the angel holding the scroll and request it from him, and that angel instructs John to eat it. In Ezekiel 2:8–3:3, the heavenly voice is the one who urges the prophet to consume the scroll, repeating the command to eat no less than four times in the Hebrew text.

In Ezekiel 3:3b, the prophet simply reports that the scroll is sweet; no one tells him in advance that this will be the case. In Revelation 10:9, the angel informs the seer that the scroll will “embitter your stomach,” but will be sweet in his mouth. This embittering after-effect does not occur in Ezekiel 3 ..."
