KJV
When I shall make the land of Egypt
desolate, and the country shall be destitute of that whereof it was full,
when I shall smite all them that dwell therein, then shall they know that I
[am] the LORD.
BSB
‘When I make the land of Egypt a desolation and empty it of all that filled it, when I strike down all who live there, then they will know that I am the LORD.’
