As learned as some people think that you are, I would assume that you do consult a Greek concordance. Saved, according to the Greek, means= delivered.
1 Tim 2:4, There is a deliverance, that is not eternal, but received as we sojourn here on earth, when a regenerated child of God comes unto the knowledge of the truth.
In Gen 33:28 God changed Jacob's name to be no more called Jacob, but to be called Israel. Thereafter when Israel is mentioned in the scriptures, it has reference to Jacob most of the time.
Rom 9:11, That the purpose of God, according to election might stand. verse 13, As it is written, Jacob have I loved, but Esau have I hated. Jacob/Israel is representative of God's elect.
Rom 10:1-3, Brethren, my heart's desire and prayer to God for Israel/Jacob is, that they might be delivered (saved). For I bear them record that they "have a zeal of God" (indicating that they are regenerated), but not according to knowledge. For they being ignorant of God's righteousness, and going about to establish their own righteousness, have not submitted themselves unto the righteousness of God.
Rom 9:6, For they are not all Israel (Jacob), which are of Israel (nation).
Rom 11;26-28, And so all Israel/Jacob shall be saved; as it is written, there shall come out of Sion the deliverer, and shall turn away ungodliness from Jacob/Israel. For this is my covenant unto them, when I shall take away their sins. As concerning the gospel, they are enemies for your sakes; but as touching the election, they are beloved for the Father's sakes.
