Here by type the Prophet is shown the illustration of the Lord's charge to him, and the tokens of the Lord's anointing him to his ministry. It is worthy remark, that Isaiah had a similar open manifestation given him at his ordination: and John the beloved Apostle, in the visions he saw. Isaiah 6:1; Revelation 10:8-10. Perhaps, by these outward tokens, it was intended to teach the Church, both ministers and people, that the words of the Lord are not to be heard or read only, but eaten and lived upon. So the Prophet Jeremiah expressed himself, Jeremiah 15:16 and Jeremiah 20:9. And if the written word be so blessed, what must be the Uncreated Word, even Christ the living bread? John 6:33, etc.
