8128. 'Speak to the children of Israel' means the influx of God's truth among those belonging to the spiritual Church. This is clear from the meaning of 'speaking' as influx, dealt with in 2951, 5481, 5797, 7270; and from the representation of 'the children of Israel' as those who belong to the spiritual Church, dealt with in 6426, 6637, 6862, 6868, 7035, 7062, 7198, 7201, 7215, 7223. The reason why 'speaking' means influx is that in the internal representative sense 'Moses' is Divine Truth, and Divine Truth enters a person's perception and thought through influx. Thought as a result of perception is inward speech, to which outward speech corresponds; and for that reason the former kind of speaking is meant in the internal sense by the latter.

7223. 'Behold, the children of Israel have not heard me' means that those who are spiritual have not received the things which have been declared to them. This is clear from the representation of 'the children of Israel' as those who are spiritual, that is, those who belong to the Lord's spiritual Church, dealt with in 6426, 6637; and from the meaning of 'not hearing' as not receiving in faith and obedience, dealt with above in 7216. The fact that the things which have been declared to them are meant, that is, things regarding their deliverance, is self-evident.
