In Genesis 39:5, this signifies celestial and spiritual good of life. (Arcana Coelestia 4982)

7723. 'Only your flocks and your herds will stay behind' means but not from good, that is to say, they may not worship the Lord from this. This is clear from the meaning of 'flock' as interior good, and the meaning of 'herd' as exterior good, both dealt with in 5913, 6048.
