Abraham had
one wife, Sarah and his God promised child with her, at the age of close to a hundred, was Isaac.
Abraham's other child Ishmael was of the works of man, because Sarah, Abraham's wife did not have
faith in God's promise of a child at such a high age. Therefor about 13 years before God fulfilled his promised child Isaac to Abraham from Sarah, Sarah took matters into her own hands, and gave her Egyptian slave Hagar to Abraham, to conceive his "promised" child, so he could have descendants, and so the poor, later to be abandoned Ishmael, was born.
Not all Abraham's descendants are saved... The whole world is blessed through Abraham, because of him, God's renewed covenant of Yeshua ha'Mashiach's / Jesus the Messiah's atonement offering reached all the nations of the earth. God's old covenant promise was inherited from Abraham by Isaac, and Jacob - not Esau, whom God "hated" - inherited from Isaac. However Jacob's descendants broke the old covenant, and it was declared nul and void.
God's old covenant people, as the descendants of Jacob received, among others, their punishment of Deuteronomy 28:64:
Deuteronomy 28 (ESV)
45 "All these curses shall come upon you and pursue you and overtake you till you are destroyed, because you did not obey the voice of the Lord your God, to keep his commandments and his statutes that he commanded you.
64 "And the Lord will scatter you among all peoples, from one end of the earth to the other, and there you shall serve other gods of wood and stone, which neither you nor your fathers have known.
But God renewed the covenant, to regather his scattered covenant people under the Kingship of Yeshua ha'Mashiach / Jesus the Messiah:
Jeremiah 31 (ESV)
27 "Behold, the days are coming, declares the Lord, when I will sow
the house of Israel (Ephramites) and the house of Judah (Jews) with the seed of man and the seed of beast.
28 And it shall come to pass that as I have watched over them to pluck up and break down, to overthrow, destroy, and bring harm, so I will watch over them to build and to plant, declares the Lord.
29 In those days they shall no longer say: "'The fathers have eaten sour grapes, and the children's teeth are set on edge.'
30 But everyone shall die for his own iniquity. Each man who eats sour grapes, his teeth shall be set on edge.
31 "Behold, the days are coming, declares the Lord, when I will make a new covenant with the house of Israel and the house of Judah,
32 not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the Lord.
33 For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people.
34 And no longer shall each one teach his neighbor and each his brother, saying, 'Know the Lord,' for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more."
Ezekiel 37 (ESV)
19 say to them, Thus says the Lord God: Behold, I am about to take the stick of Joseph (that is in the hand of Ephraim) and the
tribes of Israel associated with him. And I will join with it the
stick of Judah, and make them one stick, that they may be one (
the Church under Kingship of Yeshua ha'Mashiach / Jesus the Messiah) in my hand.
John 11 (ESV)
50 Nor do you understand that it is better for you that one man should die for the people, not that the whole nation should perish."
51 He did not say this of his own accord, but being high priest that year he prophesied that Jesus would die for the nation,
52 and not for the nation only, but also to
gather into one the children of God who are scattered abroad.

Luke 24 (ESV)
44 Then he said to them, "These are my words that I spoke to you while I was still with you, that everything written about me in the Law of Moses and the Prophets and the Psalms must be fulfilled."
45 Then he opened their minds to understand the Scriptures,
46 and said to them, "Thus it is written, that the Christ should suffer and on the third day rise from the dead,
47 and that
repentance and forgiveness of sins should be proclaimed in his name to all nations, beginning from Jerusalem.
