Here Paul refers to the Jews who rejected Jesus as "broken branches." You can translate this in an active form. Alternate translation: "But if someone broke off some of the branches" (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-activepassive]])
Here Paul speaks of the Gentile Christians as if they were "grafted branches." You can translate this in an active form. Alternate translation: "if God grafted you, a wild olive branch, among them" (See: [[rc://en/ta/man/jit/figs-metaphor]] and [[rc://en/ta/man/jit/figs-activepassive]])
The pronoun "you" is singular. Here "you" and the phrase "a wild olive branch," refer to a Gentile person, in general, who has accepted salvation through Jesus. (See: [[rc://en/ta/man/jit/figs-you]] and [[rc://en/ta/man/jit/figs-metaphor]])
