Prepared for prayer (5)
I believe the answer is:
knelt
'prepared for prayer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for knelt that I've seen before include "congregation did it" , "Went down to be knighted?" , "Rest the weight on the knees" , "adopted respectful attitude" , "Rested on the knees" .)
