<h2>The following lines exhibit figurative language from the poem:
</h2><h2></h2><h3>"So sorrow’s heaviness doth heavier grow
</h3><h3>For debt that bankrupt sleep doth sorrow owe"
</h3><h3></h3>
In the first line, the feeling of sorrow has been given the attribute of heaviness to describe how intense it is. It is said to be growing heavier, which means, it is intensifying with passing time.
In the second line, debt has been described to have slept in sorrow which is again an association of human emotion with an inanimate thing.
