"Who are Israelites; to whom pertains the adoption, and the glory, and the covenants, and the giving of the law, and the service of God, and the promises; 5 Whose are the fathers, and of whom as concerning the flesh Christ came, who is over all, God blessed for ever. Amen. 6 Not as though the word of God has taken none effect. For they are not all Israel, which are of Israel: ... 8 That is, they which are the children of the flesh, these are not the children of God: but the children of the promise are counted for the seed."
"Even unto them will I give in mine house and within my walls a place and a name better than of sons and of daughters: I will give them an everlasting name, that shall not be cut off. 6 Also the sons of the stranger, that join themselves to the LORD, to serve him, and to love the name of the LORD, to be his servants, every one that keeps the sabbath from polluting it, and takes hold of my covenant; 7 Even them will I bring to my holy mountain, and make them joyful in my house of prayer: their burnt offerings and their sacrifices shall be accepted upon mine altar; for mine house shall be called an house of prayer for all people.
8 The Lord GOD which gathered the outcasts of Israel says, Yet will I gather others to him, beside those that are gathered unto him."
