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.

2089. 'Twelve princes will he beget' means the first and foremost commandments [of faith] inhering in charity. This is clear from the meaning of 'twelve' as all things belonging to faith, and from the meaning of 'princes' as first and foremost features. King and princes are mentioned in various places in the Word, but in the internal sense they nowhere mean king or princes but the first and foremost features of the subject under discussion. That 'kings' means truths taken as a whole has been shown already in 2015, and that 'princes' means the first and foremost aspects of truth, which are commandments, in 1482. For this reason angels, especially spiritual angels, are called principalities, because they are governed by truths. Princes have reference to truths which go with charity because, as stated above in 2088, spiritual people receive charity from the Lord through truths which to them look like truths, and through charity they receive conscience.

[2] Up to now the world has not known that 'twelve' means all things of faith. Yet every time the number twelve occurs in the Word, in historical or in prophetical sections, it has no other meaning. The twelve sons of Jacob, and therefore the twelve tribes named after them, have no other meaning. And the same applies to the Lord's twelve disciples. Each one of Jacob's sons and each of the disciples represented some essential and primary aspect of faith. What each son of Jacob represented, and therefore what each tribe of Israel represented, will in the Lord's Divine mercy be discussed later on at Genesis 29, 30, where the sons of Jacob are the subject.
