Augustine of Hippo

"There has laid her waste the boar from the wood" [Psalm 80:13]. In the boar from the wood what do we understand? To the Jews a swine is an abomination, and in a swine they imagine as it were the uncleanness of the Gentiles. But by the Gentiles was overthrown the nation of the Jews: but that king who overthrew, was not only an unclean swine, but was also a boar. For what is a boar but a savage swine, a furious swine? "A boar from the wood has laid her waste." "From the wood," from the Gentiles. For she was a vineyard, but the Gentiles were woods. But when the Gentiles believed, there was said what? "Then there shall exult all the trees of the woods." "The boar from the wood has laid her waste; and a singular wild beast has devoured her." "A singular wild beast" is what? The very boar that laid her waste is the singular wild beast. Singular, because proud. For thus says every proud one, It is I, it is I, and no other.
