From the text we can assume that to dare means to be brave enough to do something.
The line reads
Say to me
"Eat in the kitchen"
So we can guess that the meaning is:
Now I am weak and others send me to eat in the kitchen, but later I wlill grow stronger and others will not be brave enough to tell me what I should do.
The above definition is very close to Oxford Dictionary of English which defines to dare as have the courage to do something
