What did Okonkwo tell the rest of his sons after Nwoye left?

From the text:

"You have all seen the great abomination of your brother. Now he is no longer my son or your brother. I will only have a son who is a man, who will hold his head up among my people. If any one of you prefers to be a woman, let him follow Nwoye now while I am alive so that I can curse him: If you turn against me when I am dead I will visit you and break your neck."
