For as ye in times past - The apostle pursues his argument in favor of the restoration of the Jews. As ye, Gentiles, in times past - for many ages back.
Have not believed - Were in a state of alienation from God, yet not so as to be totally and for ever excluded,
Have now obtained mercy - For ye are now taken into the kingdom of the Messiah; through their unbelief - by that method which, in destroying the Jewish peculiarity, and fulfilling the Abrahamic covenant, has occasioned the unbelief and obstinate opposition of the Jews.
For as ye - You who were Gentiles.
In times past - Before the gospel was preached. This refers to the former idolatrous and sinful state of the pagan world; compare Ephesians 2:2; Acts 14:16.
Have not believed God - Or have not obeyed God. This was the character of all the pagan nations.
Yet have now obtained mercy - Have been pardoned and admitted to the favor of God.
Through their unbelief - By means of the unbelief and rejection of the Jews; see the note at Romans 11:11.
