What kind of figurative language is in, Then Haste Thee, time- - 'tis kindness all ... Thou fliest and bear'st away our woes?

I think its personification but im not sure maybe im wrong, i searched it up and the other answers say hyperbole but why is it hyperbole ...

It is indeed hyperbole and not personification. this is because the poet is asking Time to take away all his woes and laying the weight of wings of kindness on it.

Explanation:

Hyperbole is when a simple act is laden with something blown out of proportion. here, the simple passage of time is said by the poet to be responsible for taking away his problems through its kindness, when the time is passing irrespective of his woes and does nothing else but pass.

it would have been personification if the winged feet of time in the quotation given, did not speed because of kindness. the human qualities are laid on time by the poet and are not presented as a foregone conclusion. hence, it is more accurate to see this as hyperbole.
