That is just lies.
There are only about 7 million Jews in Israel, and Palestine is not their "ancestral home" at all.
It is just where they temporarily ruled after they illegally invaded and wiped out the native Canaanites.
They are glorifying their massacre of millions of innocent Canaanites they murdered entirely, including women and children.
The Bible on the Hebrew invasion of the Canaanites at Jericho:
{...
Joshua 6:22-25
Contemporary English Version
21-25 They killed everyone, men and women, young and old, everyone except Rahab and the others in her house. They even killed every cow, sheep, and donkey.
Joshua said to the two men who had been spies, “Rahab kept you safe when I sent you to Jericho. We promised to protect her and her family, and we will keep that promise. Now go into her house and bring them out.”
The two men went into Rahab's house and brought her out, along with her father and mother, her brothers, and her other relatives. Rahab and her family had to stay in a place just outside the Israelite army camp.[
a] But later they were allowed to live among the Israelites, and her descendants still do.
The Israelites took the silver and gold and the things made of bronze and iron and put them with the rest of the treasure that was kept at the Lord's house.[
b] Finally, they set fire to Jericho and everything in it.
