Like "say," the word "speak" refers to thoughts and feelings moving from our more internal spiritual levels to our more external ones -- and ultimately from the Lord, who is in a sense the most internal spiritual level of all. This is generally called "influx" and "perception" in the Writings, meaning they are thoughts and feelings that flow in in a complete way from the Lord, rather than being things we have to think about and figure out. On a number of occasions "speak" and "say" are used together; in these cases "speak" refers more to intellectual instruction in matters of thought and "say" refers more to feelings and affections that flow in directly.

10179. 'A cubit shall be its length, and a cubit its breadth' means consisting equally of good and of truth. This is clear from the meaning of 'length' as good, and of 'breadth' as truth, dealt with in 1613, 3433, 3434, 4482, 9487. Consisting of the two equally is meant by the fact that the length was a cubit and the breadth a cubit, thus by the fact that they were of equal measure; for in the Word measures are used to specify the amount and essential nature of a reality, and numbers are used in the specification. The reality specified by the measure here - a cubit - is good and truth, the former being meant by 'length' and the latter by 'breadth'. The reason why good is meant by 'length' is that the length is measured from east to west, and good from one boundary to the other is meant by 'east and west', whereas the breadth is measured from south to north, and truth from one boundary to the other is meant by 'south and north'. The same holds true in heaven. There the Lord is the Sun and also the East, the point from which every position there is determined. Those who live before the face of the sun enjoy a perception of good in the measure that they are near or far from it. Those with a clear perception of good are in the east, 3708, 9668, while those with a dim perception of good are in the west, 3708, 9653. Those however who see things in the clear light of truth are in the south, 9642, whereas those who see them in the dim light of truth are in the north, 3708. So it is that such things are meant in the Word by those four quarters, and that good is meant by 'length', and truth by 'breadth'.
