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.

2542. 'And spoke all these words in their ears' means an exhortation made to confirmations from this source, even until they should become obedient. This becomes clear from the train of thought in the internal sense, and also from the meaning of 'ears'.

From the train of thought: There are many matters of a confirmatory nature that lend support to whatever the rational acknowledges; indeed its acknowledgement is due entirely to those confirmatory matters. This is why, when rational concepts are brought into a condition of obedience, an exhortation is made to things that confirm, for these are for ever at hand and so to speak rising up.

From the meaning of 'ears': 'Ears' in the internal sense of the Word means obedience because of the correspondence that exists between hearing and obeying. Furthermore, this correspondence lies hidden within the very word 'hearing', more so in 'hearkening'. This correspondence has its origin in the next life where those who are obedient and willing belong to the province of the ear. Indeed they correspond to the faculty of hearing itself, an arcanum unknown as yet. But these matters will be seen more easily when correspondence will be dealt with in the Lord's Divine mercy later on. The fact that 'ears' has this meaning becomes clear from very many places in the Word; but for the time being let only the following in Isaiah be quoted,

Make the heart of this people fat and their ears heavy, and plaster over their eyes, lest they see with their eyes and hear with their ears, and their heart understands. Isaiah 6:10.

Here 'seeing with the eyes' means understanding, and 'hearing with the ears' means perceiving with affection and therefore means obeying. And nothing else is meant when the Lord says,

He who has an ear to hear, let him hear. Matthew 11:15; 13:9, 43; Luke 8:8; 14:35.
