What does Exodus 3:19 mean?

John Gill's Exposition of the Bible
Exodus 3:19

And I am sure that the king of Egypt will not let you go
Or "but" F3 "I am sure" though so reasonable a request was made him, yet it would not be granted; this is observed to them, that they might not be discouraged when he should refuse to dismiss them, which the omniscient God knew beforehand, and acquaints them with it, that, when it came to pass, they might be induced to believe that the mission of Moses was of God, rather than the contrary: no, not by a mighty hand;
the mighty power of God displayed once and again, even in nine plagues inflicted on him, until the tenth and last came upon him; or "unless by a mighty hand" F4, even the almighty hand of God; prayers, entreaties, persuasions, and arguments, will signify nothing, unless the mighty power of God is exerted upon him.
