Romans 11:16, 28

If the first portion [of dough offered as the first fruits] is holy, so is the whole batch; and if the root (Abraham, the patriarchs) is holy, so are the branches (the Israelites). [Num 15:19-21]

From the standpoint of the gospel, the Jews [at present] are enemies [of God] for your sake [which is for your benefit], but from the standpoint of God’s choice [of the Jews as His people], they are still loved by Him for the sake of the fathers.
