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.

I was allowed to see what happened when spirits belonging to that planet became angels. Bright horses as if of fire appeared, and these took them away in the same manner as Elijah was taken, the bright horses as if of fire serving to mean an enlightened understanding. In the Word horses mean the power of understanding, see 2760-2762, 3217, 5321, 6125, 6534; and 'the fiery horses' and 'the fiery chariots' that took Elijah away mean an understanding of the inner contents of the Word, 2761.
