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.

5603. 'And Judah said to Israel his father' means a perception received from the good of the Church regarding these matters. This is clear from the meaning of 'saying' in the historical narratives of the Word as perceiving, often dealt with already; from the representation of 'Judah' as the good of the Church, dealt with above in 5583; and from the representation of 'Israel' as the internal spiritual Church, dealt with in 3305, 4286. From this it is evident that 'Judah said to Israel his father' means a perception the Church had which it received from its own good.
