But I ask, "Did not they [i.e., the Jews] hear [the message]?" Certainly they did! [Psa. 19:4 says], "The sound [of their preaching] went out into all the world, and their message reached to the ends of the earth."

But Isaiah said about the Israelites [Isa. 40:2], "I reached out all day long to [help] people who disobeyed and spoke against [me]."

Therefore, you should not brag [about your superiority] over the [natural] branches [i.e., the rejected Jews]. But, if you must brag, it should not be over you [Gentiles] nourishing the roots [i.e., the Jews], but over the roots nourishing you.
