Romans 9:6-8, "However, it is not as though Yahweh's plan had failed. For it is not everyone who is a descendant of Israyl who belongs to Israyl. Nor, just because they are his descendants, are they all Abraham's children; but: In Isaac will your seed be called. That is, it is not those who are the children of the flesh who are Yahweh's children; but it is the children of the promise who are regarded as Abraham's seed."
Psalm 105:6-9, "O seed of Abraham His servant, You children of Yaaqob, His chosen ones! He is Yahweh our Father! His judgments are in all the earth. He has remembered His covenant forever, the Law He commanded for a thousand generations; Which He made; ratified, established, with Abraham, and vowed by His oath to Isaac. He confirmed it; let it stand, to Yaaqob for a Law, and to Israyl for an everlasting covenant."
Galatians3:28,29, "Is there not the Yahdai as well as the Greek; Gentile? Is there not the slave as well as the freeman? Is there not the male and the female? For all of you must be in unity in Yahshua Messiah. And if you are in Messiah, then you are a seed of Abraham, heirs according to the promise."
Psalm 89:26-37, "He will call out to Me; You are my Father, O Yahweh! You are the Rock of my salvation! And I will make Him My firstborn, higher than the kings of the earth. My mercy I will keep for Him forever and My covenant will stand fast with Him. And I will establish his Seed forever, and his throne will be as the days of heaven. Should his children forsake My Law, and refuse to walk in My judgments; Should they profane My statutes, and fail to keep My commandments; Then I will punish their transgression with the rod, and their iniquity with lashes from the whip. Nevertheless, My lovingkindness I will not utterly withdraw from him, nor will I ever betray My faithfulness. My covenant I will not break, nor will I change the what (Law) that has gone out of My lips. Once for all, I have vowed by My holiness--I cannot lie, and I say to David: His Seed will endure forever, and his throne will endure before Me like the sun. His throne will be established forever like the moon: the faithful witness in the sky."
