Exodus 6:1

Then the Lord said unto Moses
In answer to the questions put to him, and the expostulations made with him: now shalt thou see what I will do to Pharaoh:
in inflicting punishments on him: for with a strong hand shall he let them go; being forced to it by the mighty hand of God upon him; and it is by some rendered, "because of a strong hand" ^F19; so Jarchi; for this is not to be understood of the hand of Pharaoh, but of the hand of God: and with a strong hand shall he drive them out of his land:
not only be willing that they should go, but be urgent upon them to be gone, ( Exodus 12:33 ) .
