May you never be reft

‘To reave’ is an archaic verb meaning to carry out raids for plunder, or to rob somebody by force, with the past tense of ‘reft’.  

There is a vestige of this in the still current words ‘bereave’ and ‘bereft’, used mostly in the sense of grieving for someone who has been lost to you; presumably the implication is that you feel you have been robbed of their presence.  A ‘bereavement’ is a gentle way of referring to someone you love having died. 

‘Nobody knows / where these reavers from hell roam on their errands.’
