6989. Or deaf. That this signifies no perception of truth, and consequently no obedience, is evident from the signification of the “deaf,” as being those who do not perceive what truth is, and consequently do not obey; thus abstractedly, no perception of truth, and consequently no obedience. That the “deaf” have this signification is because hearing corresponds both to perception and to obedience—to perception because what is heard is inwardly perceived, and to obedience because it is thence known what ought to be done. (That this is the correspondence of hearing, and also of the ear, see n. 3869, 4652-4660, 5017.) Hence it is evident what is signified by the “deaf.” In the Word by the “deaf” are also signified the nations which do not know the truths of faith, because they have not the Word, and therefore they cannot live according to these truths; nevertheless when they have been instructed, they receive them and live according to them. These are meant in Isaiah:

Then shall the eyes of the blind be opened, and the ears of the deaf shall be opened (Isaiah 35:5).

Hear ye deaf, and look ye blind, seeing (Isaiah 42:18).

In that day the deaf shall hear the words of the book; and out of thick darkness, and out of darkness, the eyes of the blind shall see (Isaiah 29:18).

Bring forth the blind people that have eyes, and the deaf that have ears (Isaiah 43:8);

by the “deaf” are here meant those who by the coming of the Lord came into a state of receiving the truths of faith, that is, of perceiving them and obeying them. The same are signified by the “deaf” whom the Lord healed (Mark 7:31; 9:25). Because the “deaf” signified such, it was forbidden those with whom the representative church was instituted “to curse the deaf and to put a stumbling-block before the blind” (Leviticus 19:14).

5017. And it came to pass when he heard. That this signifies when it was perceived, is evident from the signification of “hearing,” as being to obey, and also as being to perceive. That it means to obey may be seen above (n. 2542, 3869); that it means also to perceive is plain from the very function of the ear, and hence from the nature of the hearing. The function of the ear is to receive another’s speech and convey it to the common sensory, in order that the sensory may perceive what the other person is thinking, so that “to hear” is to perceive. Thus it is the nature of the hearing to transfer what anyone is speaking from his own thought into the thought of another, and from the thought into his will, and from the will into act; hence “to hear” is to obey. These two offices are proper to the hearing. In the languages these are distinguished by “hearing” anyone, which is to perceive, and by “listening,” or “hearkening” to anyone, which is to obey. That these two offices belong to hearing is because man cannot communicate the things of his thought, and also the things of his will, by any other way; nor can he otherwise persuade and by reasons induce others to do and to obey what he wills. From all this it is evident by what a circle communications are effected-from will into thought, and so into speech; and from speech through the ear into another’s thought and will. Hence also it is that the spirits and angels who correspond to the ear or to the sense of hearing in the Grand Man, are not only perceptions, but also obediences. That they are obediences, may be seen above (n. 4652-4660); and because they are obediences, they are also perceptions, for the one involves the other.
