The Children of Israel were told to keep three feasts each year - the feast of unleavened bread, the feast of first fruits, and the feast of ingathering. Should we still do that?

In Exodus 23:14-16, Moses receives the instructions about these feasts. Those three verses in Exodus comprise our brief story. Their inner meaning is explained in Arcana Coelestia 9286-9296.

There are three feasts. In the Word, the number three represents a completeness, a sense of things being covered from beginning to end. Our thankfulness to the Lord is supposed to keep going - to endure.

The first feast, of unleavened bread, stands for worship, for our thankfulness for the Lord's action in our minds to get rid of false ideas. That enables us to start to receive good loves.

The second feast, of first fruits, relates to the planting of true ideas in that "soil" of initial loves for doing good.

The third feast, of harvest, or ingathering, stands for the time when, by applying our true ideas, we receive real good - loves of the neighbor and of the Lord - that become the middle of our lives. This is the state of rebirth, where we have - by working through the year (our lives), and enduring in thankfulness, allowed the Lord to get rid of our false ideas, and push our evil loves to the periphery, so that good can work, and be fruitful.

These feasts, then, represent the progress of our spiritual lives. In some manner, we need to keep them.

7780. 'Even to the firstborn of the servant-girl who is behind the mill' means falsified truths of faith that occupy the very last place. This is clear from the meaning of 'the firstborn' as faith, dealt with immediately above in 7779, and since faith is meant, so is truth in its entirety because truth, being that which one ought to believe, is the component of faith; and from the meaning of 'a servant-girl' as a rather external affection for truth, or an affection for knowledge, dealt with in 1895, 2567, 3835, 3849, and 'the servant-girl behind the mill' as the most external affection for knowledge since 'behind the mill' means that which occupies the very last place. The expression 'behind the mill' is used because 'the mill' has reference to matters of faith. For by means of a mill grain is ground into flour and so prepared for making bread, and 'flour' means truth which results in good, 'bread' the actual good that results from it. Thus 'sitting at the mill' is acquiring and learning the kinds of things that will be of service to faith, and through faith of service to charity. This is why when the ancients described learning the basic elements of faith they described it as 'sitting at the mill', or learning elements even more basic as 'sitting behind the mill'. It is because such things were meant that in His teachings about the final period of the Church the Lord says,

Two women grinding at the mill; one will be taken and the other will be left behind. Matthew 24:41.

These words would never have been used if 'the mill' had not meant matters of faith. For what 'the mill' and 'grinding' mean in the internal sense, see 4335. With regard to the truths of faith that occupy the first place and those that occupy the very last, it should be recognized that the truths of faith which emanate directly from the good of charity occupy the first place, for they are the outward form taken by good, whereas the truths which occupy the last place are bare truths. For when truths derive in succession from good, each degree of them departs further away from it, till at length they become bare truths. This is the kind of truths meant by 'servant-girls behind mills'.
