Apollo and the Furies argue about whether the matricide was justified; Apollo holds that the bond of marriage is sacred and Orestes was avenging his father, whereas the Erinyes say that the bond of blood between mother and son is more meaningful than the bond of marriage. They invade his temple, and he says that the matter should be brought before Athena. Apollo promises to protect Orestes, as Orestes has become Apollo's supplicant. Apollo advocates Orestes at the trial, and ultimately Athena rules in favor of Apollo.
