Which line in this excerpt from Blake's "The Chimney Sweeper" uses assonance?
Then naked & white, all their bags left behind,
They rise upon clouds, and sport in the wind.
And the Angel told Tom, if he'd be a good boy,
He'd have God for his father & never want joy.

And so Tom awoke; and we rose in the dark
And got with our bags & our brushes to work.
Though the morning was cold, Tom was happy & warm;
So if all do their duty, they need not fear harm.
