Now we know that whatsoever things the law says, it says to them who are under the law: that every mouth may be stopped, and all the world may become guilty before God.

Ambrosiaster
AD 400
It is clear that the law censures those who did not believe first of all their leader Moses nor their ancestors the prophets, whom they killed, nor the apostles who were their kinsmen according to the flesh, whose blood they spilled. They were always ungodly and rebellious against God, so as to be condemned by the law whose authority they thought should be despised. Paul says this because with the Jews bound in sin the whole world has become subject to God. For there is no doubt that the pagans were immersed in sins and wickedness and that for that reason the whole world bowed before God in order to obtain forgiveness. The “whole world” means Jews and Gentiles, from whom believers are set apart. Therefore when Paul affirms that the Jews, who had received God’s law and to whom the promise had been given, were bound in sin, there is no doubt that all the Gentiles were guilty of death … for all have been found guilty and need the mercy of God, whether they be Jews or Gentiles.
