7705. 'Not one locust was left in all the border of Egypt' means that those falsities in the outermost parts no longer made their appearance. This is clear from the meaning of 'locust' as falsity. And since it is falsity in outermost parts, 7643, the phrase 'in all the border of Egypt' is used; for 'the border' is the outermost part, and 'Egypt' the natural. The fact that 'not a locust was left' means that none made an appearance is self-evident. For something similar said regarding 'the hail', see 7611.
