In Zechariah 2:4, this signifies the church of people who will receive the Divine proceeding of the Lord on a deep level within themselves. (Apocalypse Explained 629[6])

6902. 'And you are to say to him' means influx. This is clear from the meaning of 'saying' as influx, dealt with in 5743, 6152, 6291. The reason why 'saying' here is influx is that the communication dealt with in 6901 - the communication of such truths as belong to the law from God, and to intelligence acquired from that source - is effected by means of influx.
