Andrey Tikhomirov - The Exodus. Scientific line-by-line explanation of the Bible стр 10.

7 Then Pharaohs servants said to him, «How long will he torment us?» Let these people go, let them serve the Lord their God; dont you see yet that Egypt is dying? (In Egypt, apparently, the situation was getting worse).

8 And they brought Moses and Aaron back to Pharaoh, and [Pharaoh] said to them, Go, do the service of the LORD your God; who then and who will go? (Again, it seems to let go).

9 And Moses said, Let us go with our young and our old, with our sons and our daughters, and with our sheep and with our oxen, for we have a feast to the LORD. (Lets go with the whole camp).
