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.

10536. 'And no one put on his finery' means the nature of their external which is such that it lacks what is Divine. This is clear from the meaning of 'finery' as the presence of what is Divine in external things, so that 'not putting on his finery' means the absence of what is Divine in those things. The reason why 'finery' has this meaning is that 'finery' relates to clothing, and Divine Truths are meant by clothing generally. The reason why Divine Truths are meant by clothing generally lies in things in the next life that are representative. All there, both angels and spirits, appear clothed in garments, each one in garments that accord with his truths. Those in possession of truths that are authentic and come from God appear clothed in brilliantly white garments; others appear in others different from these. Spirits indeed do not know where their garments come from; they are clothed without their knowing how. And also the garments they wear are varied, as determined by the changes of state they undergo in respect of truths. In short, the character of their understanding is what is revealed and represented by their garments; for everyone's understanding is shaped by truths and comes to have the same nature as the truths which compose it. The understanding which angels in heaven possess resides on an inner level with them, as a consequence of which their garments are brilliant and white. The brilliance is due to Divine Good, and the whiteness to the light of heaven, which is Divine Truth. But the garments of those whose interest lies in external things and not in what is internal are drab and torn, like those of beggars in the streets or robbers in the forests. From all this what is meant by 'finery' may be seen, namely the Church's holy truths, and therefore 'not putting on finery' means the absence of the Church's holy truths, and in reference to the Israelite nation, whose interest lay in external things and not in what was internal, means the nature of their external which was such that it lacked truths from God.

Truths are meant by 'garments', see 2132, 2576, 4545, 4763, 5248, 5319, 5954, 6378, 6914, 6917, 6918, 9093, 9158, 9212, 9216, 9814, 9827, 9952.
