Elixer clept, we sechen faste echoon;
For hadde we hym, thanne were we siker ynow.
But unto God of hevene I make avow,
For al oure craft, whan we han al ydo,
And al oure sleighte, he wol nat come us to.
He hath ymaad us spenden muchel good,
For sorwe of which almoost we wexen wood,
But that good hope crepeth in oure herte,
Supposynge evere, though we sore smerte,
To be releeved by hym afterward.
Swich supposyng and hope is sharp and hard;
I warne yow wel, it is to seken evere.
That futur temps hath maad men to dissevere,
In trust therof, from al that evere they hadde.
