A "field" in the Bible usually represents the Lord's church, and more specifically the desire for good within the church. It's where good things start, take root, and grow. When you have a desire to be a good person and to do good things, the natural first questions are "What does that mean?", "What should I do?", "What can I do?". You look for ideas, concepts, direction. Once you figure out something you want to do or a change you want to make in yourself, you seek specific knowledge. If you want to volunteer at a food pantry, say, you'd need to know whom to call, when they need help, where to go, what to bring. Armed with that knowhow, you're ready to get to work. That process could be compared to food production. You start with a field -- which is that desire to be good. Then you plant seeds -- those ideas and concepts. Those seeds sprout into plants -- the specific facts and knowledge needed for the task (easily seen in the food pantry example, but also true with deeper tasks like "being more tolerant of my co-workers" or "taking more time for prayer," or "consciously being a more loving spouse"). Finally, those plants produce food -- the actual good thing that you go and do. The Writings also say that in a number of cases a "field" represents the doctrine, or teachings, of the church. This sounds markedly different. The desire for good is emotional, a drive, a wanting; doctrine is a set of ideas. But for a church to be true, its doctrine must be centered on a desire for good, and must lead people toward doing what is good. So sound doctrine is actually closely bound up with the desire for good.

The Philistines play a large role in the Bible as one of the longest-standing and most bitter rivals of the people of Israel, clashing with them in repeated wars. The Philistines were a remnant of the Ancient Church, or church of Noah, but had turned the deep wisdom of that church into a worship that focused solely on knowledge of religious ideas and the details of ritual, with no concept of putting religious ideas to work in living a good life. People would be esteemed for their knowledge, no matter how evil they might be in their lives. This was a particularly attractive trap for the people of Israel, who lived in a state of obedience to a long list of spiritually meaningful rules. It was easy for them to forget about the “obedience” part and focus instead on the “rules” part, which made them akin to the Philistines. This is also a threat to us in our own lives. We need to remember that simply knowing a lot and believing the right things will not make us good people -- we have to use that knowledge to treat other people in a loving, caring way.

In 1 Samuel 5,6, this signifies people in faith separated from charity. (Divine Providence 326[12])

In Jeremiah 47:2, 3, this represents people who hold false ideas, and reason about spiritual things from them. (Arcana Coelestia 705) Philistia signifies this religion. (Arcana Coelestia 727)
