P The Hour Of My Departure Come

The hour of my departure come
now let me die in peace.

Alexander Greig

Whilst not quite a direct quote it appears to be from the first verse of the hymn The hour of my dpearture's come.
The hour of my departure’s come;
I hear the voice that calls me home;
at last, O Lord! let trouble cease,
and let thy servant die in peace.

The full hymn
1 The hour of my departure’s come;
I hear the voice that calls me home;
at last, O Lord! let trouble cease,
and let thy servant die in peace.
2 The race appointed I have run;
the combat’s o’er, the prize is won;
and now my witness is on high,
and now my record’s in the sky.
3 Not in mine innocence I trust;
I bow before thee in the dust;
and through my Saviour’s blood alone
I look for mercy at thy throne.
4 I leave the world without a tear,
save for the friends I held so dear;
to heal their sorrows, Lord, descend,
and to the friendless prove a friend.
5 I come, I come, at thy command,
I give my spirit to thy hand;
stretch forth thine everlasting arms,
and shield me in the last alarms.
6 The hour of my departure’s come;
I hear the voice that calls me home:
now, O my God! let trouble cease,
now let thy servant die in peace.

Whilst from a hymn the memorial is unique, and seems to almost be written by (or for) the person who passed. It is very unique.
