864. Verse 7 And he sent out a raven, and it went out going back and forth until the waters dried up from over the earth.

'He sent out a raven, and it went out going back and forth' means that falsities were still giving trouble; 'a raven' means falsities, 'going back and forth' means that such was their state. 'Until the waters dried up from over the earth' means the apparent dispersal of falsities.
