‘Passes by your ears’ in the passage means

You all know how friendly we are with Okperi. Do you think that any Umuaro man who goes to prison there will come back alive? But that apart, do you forget that this is the moon of planting? Do you want to grow this year’s crops in the prison house in a land where your fathers owe a cow? I speak as your elder brother. I have travelled in Olu and I have travelled in Igbo and I can tell you that there is no escape from the white man. He has come when suffering knocks at your door and you say there is no seat left for him, he tells you not to worry because he has brought his own stool. The white man is like that. Before any of you here was old enough to tie a cloth between the legs I saw with my own eyes what the white man did to Abame. Then I knew there was no escape. As day light chases away darkness so will the white man drive away all our customs. I know that as I say it now it passes by your ears, but it will happen. The white man has power which comes from the true God and it burns like fire. This is the God about whom we preach every eighth day………..
Unachukwu’s opponents were now shouting that this was a meeting of an age group that they had not assembled to join with him in chewing the seed of foolishness which they called their new religion.
‘We are talking about the white man’s road’ said a voice above the others.
‘Yes, we are talking about the white man’s road. But when the roof and walls of a house fall in, the ceiling is not left standing. The white man, the new religion, the soldiers, the new road-they are all part of the same thing. The white man has a gun, a machete, a bow and carries fire in his mouth. He does not fight with one weapon alone’.
