The Lord puts a difference between His
people (the Israelites) and those who are
strangers to Him, as were the Egyptians,
and the difference is the difference between
life and death. Read Exodus 11:7

He draws a line, on the side of life. . . life
more abundantly, life for the spirit, soul and
body; and on the other side of which is death
. . . .death for spirit, soul, and body, the second
death.
