Micah 7:20

Thou wilt perform the truth to Jacob and the mercy to Abraham -What was free mercy to Abraham, became, when God had once promised it, His truth. Abraham also stands for all those, who in him and his Seed should be blessed, those who were “aliens from the commonwealth of Israel, and strangers from the covenants of promise, having no hope, and without God in the world”Ephesians 2:12, in no covenant or relation with God, as well as those who were the children of the faith; pagan, as well as Jews. Jacob represents these who were immediately his children, such of the children of Israel, as were also the true Israel and children of faithful Abraham.
