'Being sent' means coming forth, (or going forth), in the internal sense, as in John 17:8. In similar manner, it is said of the holy of the spirit, that it was 'sent,' that is, it goes forth from the divine of the Lord, as in John 15:26, 16:5, 7.

So, too, the prophets were called 'the sent,' because the words which they spoke went forth from the holy of the spirit of the Lord.

'To be sent,' as in Genesis 37:13, signifies teaching.

7934. 'That you shall keep this service' means worship because of the deliverance. This is clear from the meaning of 'keeping' as that which is to be observed, as above in 7930a; and from the meaning of 'serving' or 'service' as worship of the Lord.
