Which lines in the poem express the view that death is an enviable state that frees the departed from the miseries of the body and old age?

farewell, thou child of my right hand, and joy ;
[ my sin was too much hope of thee, lov'd boy. ]
seven years thou wert lent to me, and i thee pay,
[ exacted by thy fate, on the just day. ]
oh, could i lose all father now ! for why
[ will man lament the state he should envy?
to have so soon 'scaped world's and flesh's rage,
and if no other misery, yet age ! ]
rest in soft peace, and, asked, say, here doth lie
ben jonson his best piece of poetry.
[ for whose sake henceforth all his vows be such ]
as what he loves may never like too much.
