Notice, rather than leaving all physical possessions behind like those pioneers needed to do to lighten their load, God provided much more physically for their journey. They added great material possessions from the spoils of Egypt before their journey out began with setting sun that started the 15th day, and the first day of Unleavened Bread.
Notice it says in verse 35 that they had done all this at the word of Moses.
In Exodus 12:33, the Passover has occurred; and Pharaoh has sent his message.
Notice, they did not say this—they were not that urgent; they were not that concerned—to give the Israelites things—payment for all their years of wages that was owed to them—until after the killing of the firstborn. Now they were throwing things at them! "Here, take it. Get! Get out of here. Go away. Leave!"
Proposal number one was beginning to be accomplished; they were being set free by the very word of their captors. Their taskmasters were saying, "Get out of here."
