Ezekiel 2:8

Open thy mouth and eat that I give thee - Take my word as thou wouldst take thy proper food; receive it into thy heart; ponder it there, that it may be the means of strengthening and preserving thy soul, as proper nourishment will strengthen the body, and preserve from death. And the people to whom such messages of God may come should so hear it read, mark, learn, and inwardly digest it, that it may become efficient nourishment to their souls.
