# flesh and blood

This expression refers to people, not spirits who do not have human bodies. (See: [[rc://en/ta/man/jit/figs-synecdoche]])

# against the powers over this present darkness

Here it is implied that "the powers" refers to powerful spiritual beings. Here "darkness" is a metaphor for things that are evil. Alternate translation: "against the powerful spiritual beings that rule over people during this present evil time" (See: [[rc://en/ta/man/jit/figs-explicit]] and [[rc://en/ta/man/jit/figs-metaphor]])
