And at the end of is literally “And it was [or, happened] at the end of.” On that very day is emphatic, to show that the actual day of the exodus was also “the day the 430 years ended.” New Jewish Publication Society’s Tanakh has “At the end of the four hundred and thirtieth year, to the very day.”

All the hosts of the LORD refers to “all the tribes of the LORD’s people,” or “all the companies of the LORD” (New Revised Standard Version). New Jerusalem Bible has “all Yahweh’s armies,” but see the comment at verse 17 on the meaning of hosts. Went out from the land of Egypt simply means they “left Egypt” (Good News Translation).

It is possible to combine verses 40 and 41 as follows:

• All the tribes of the LORD’s people left Egypt exactly four hundred thirty years after they had arrived there.
