Ezekiel was sent to the people of Israel to speak God’s words to them. Before he did, he was to eat those words himself.
Ezekiel 2:8-3:3
But you, son of man, hear what I say to you. Be not rebellious like that rebellious house; open your mouth and eat what I give you.” And when I looked, behold, a hand was stretched out to me, and behold, a scroll of a book was in it. And he spread it before me. And it had writing on the front and on the back, and there were written on it words of lamentation and mourning and woe. And he said to me, “Son of man, eat whatever you find here. Eat this scroll, and go, speak to the house of Israel.” So I opened my mouth, and he gave me this scroll to eat. And he said to me, “Son of man, feed your belly with this scroll that I give you and fill your stomach with it.” Then I ate it, and it was in my mouth as sweet as honey.
Ezekiel was to fill himself with the Word of God, and then he would be ready to speak for God. Similarly, if we will read the Word of God a lot and fill ourselves with it, then we’ll be ready to speak it mightily.
Ezekiel also mentioned that when he ate God’s words, they were sweet to him.
Psalm 119:103
How sweet are your words to my taste, sweeter than honey to my mouth!
