"Three times! — you know the fable, —
(I'll make it thirty," muttered he,
"But I will lay the cable!")”

Revelations of Divine Love (c. 1393), Chapter 3
Context: When I was thirty years old and a half, God sent me a bodily sickness, in which I lay three days and three nights; and on the fourth night I took all my rites of Holy Church, and weened not to have lived till day. And after this I languored forth two days and two nights, and on the third night I weened oftentimes to have passed; and so weened they that were with me.
And being in youth as yet, I thought it great sorrow to die; — but for nothing that was in earth that meliked to live for, nor for no pain that I had fear of: for I trusted in God of His mercy. But it was to have lived that I might have loved God better, and longer time, that I might have the more knowing and loving of God in bliss of Heaven. For methought all the time that I had lived here so little and so short in regard of that endless bliss, — I thought nothing.
