Without a moment's warning

From Depot Road Cemetery, Leverett. MA:

In memory of the Rev. Henry Williams A.M.
who was the first ordained minister
of the Church of Christ in Leverett.
He was an ardent preacher,
eminent in prayer.
A faithful minister,
and of truly evangelical sentiments.
Borne down with infirmity and pain,
which he long endured with Christian
patience and submission, he expired
suddenly in his chair, without a
moment's warning, Nov. 27, 1811
Aged 66
"Blessed is that servant, whom his Lord, when he
cometh, shall find so doing."
