well John the Baptist ate dried locusts and honey
The Bible doesn't give the rest of the story, so this is just my opinion. When a preacher is starving to the point that he must subsist on bugs to survive, that says more about his congregation than it does him.
Whenever I get to that part of the book, I ask, Why didn't you people bring him some good food, at least a sandwich for crying out loud???
He read, studied (hard work) and preached the Bible the good news of Jesus Christ. He baptized and warned against those who were bringing evil and judgement upon them. He did the work of God to provide their spiritual needs, yet they would not meet his physical needs. God's people do this. I've been guilty of not preaching on this because there are the TV preachers who beg for $ and make tens of millions preaching lies. We go to the opposite extreme and don't ask for needs to be met and most Christians usually neglect to give as they should. 10% Is less than gt demands and most give less than 1% to God's servants . Hence, John the Baptist ends up foraging for food while laboring to meet the greater needs of others, neglecting self for their sakes.
Nobody brought Jesus and his men any food that we know of amongst thousands of families, but Jesus provided for them when they had no other way.
Anyhow, I do agree with you about John eating locusts. As an example that is the truth. I just don't think it's a doctrine or direction that God recommended by the mention of that. The commands were to eat the Passover lamb, partake of the sacrifices once they had been offered, eat clean animals, bread, herbs, fruit. But he had to survive on something.
Again, it's a book in progress 😉.
