A son of Abraham was Isaac and a son of Isaac was Jacob. Jacob's name was changed to Israel:
Genesis 32:24-28
24 And Jacob was left alone; and there wrestled a man with him until the breaking of the day.
25 And when he saw that he prevailed not against him, he touched the hollow of his thigh; and the hollow of Jacob’s thigh was out of joint, as he wrestled with him.
26 And he said, Let me go, for the day breaketh. And he said, I will not let thee go, except thou bless me.
27 And he said unto him, What is thy name? And he said, Jacob.
28 And he said, Thy name shall be called no more Jacob, but Israel: for as a prince hast thou power with God and with men, and hast prevailed.
The posterity of Israel is known as the House of Israel. Israel had 12 sons and one daughter and these are their names. From them come the twelve tribes of Israel:
Sons of Leah
1. Rueben
2. Simeon
3. Levi
4. Judah
9. Issachar
10. Zebulun
(Dinah a daughter)
Sons of Bilhah
5. Dan
6. Naphtali
Sons of Zilpah
7. Gad
8. Asher
Sons of Rachel
11. Joseph
12. Benjamin
The Jews are the posterity of Judah. Through this lineage, Jesus Christ the Savior was born. Later Joseph had two sons named Ephraim and Manasseh. These two were eventually adopted by Israel and are also numbered among the tribes of Israel. See Genesis 47-48. This is why we see Manasseh's name mentioned in the restoration of the tribes of Israel in Revelation 7. Ephraim is the tribe of Joseph mentioned. Basically Joseph, who won the birthright was given a double portion and those portions went to Ephraim who received the birthright under Joseph and to his other son Manasseh. Notice in Revelation 7 that Judah is mentioned as one of the tribes of Israel and thus are numbered among the house of Israel.
