Isaac (Yitschaq)  is the son Abraham (Avaraham) offered as a sacrifice to Yah on Mt. Moriah (Moriyah).

 Isaac (Yitschaq)  is the son Abraham (Avaraham) offered as a sacrifice to Yah on Mt. Moriah but sacrificed a ram instead.

Isaac's name means laughter because when the angel of Yah told Sarah she would conceive in her old age she laughed.  When he was born Abraham was 100 and Sarah was 99 years old.  After eight days he was circumcised and he was weened at age two years old.

After his mother Sarah died  Abraham sent his servant to find him a wife. Inspired by Yah;  he found Isaac a wife whose name was Rebekah (Rivqah).  The servant gave Rebekah's  and her father expensive gifts and then took her to meet Isaac.    When Rebekah saw Isaac it was  love at first sight they  married.

 They had  twin sons  Jacob and Esau.  They were fighting in her womb.  Rebekah inquired of Yah why there was so much commotion in her womb Yah told her there were two distinct, diverse nations in her womb.  Issac loved Esau and Rebekah loved Jacob. Jacob who is Israel and Esau who is Edom until this day.

Isaac has seven half brothers but the one most talked about is  of course Ishmael whose mother was Hagar.  They the Arab nations today.

After Sarah died Abraham remarried.  His wife's name wad Kethura  (Qethurah) who had six sons.

I saw  a video on You Tube claiming that  there is proof  that the descendents of Jokshan are Koreans.  When I find it again will post a link for you.
