# There is no sorcery that works against Jacob ... no fortune-telling harms Israel

These two lines mean the same thing, that no curse that anyone puts on the nation of Israel will be effective. Here "Jacob" is a metonym that refers to Israel. (See: [[rc://en/ta/man/jit/figs-parallelism]] and [[rc://en/ta/man/jit/figs-metonymy]])

# it must be said

This can be stated in active form. "people must say" (See: [[rc://en/ta/man/jit/figs-activepassive]])

# Look what God has done!

It is implied that what God did for them was good. Alternate translation: "Look at the good things God has done for them!"
