The sons of the northern king attack the south (Dan 11:10-11:10)

“The sons of the northern king

Shall wage war.

They shall assemble

A multitude

Of great forces.

They shall advance

Like a flood.

They shall pass through.

They shall again carry the war

As far as his fortress.”

The sons of the northern King Seleucus II were King Seleucus III (225-223 BCE) and King Antiochus III (222-187 BCE) both of whom ruled after him. They decided to attack the southern king of Egypt. They assembled a great army and advanced like a flood to the fortress of Egypt.
