beireR.16.173: According to OED2, s. v.
bo (a. and pron.) and both (a. and adv.), R's unique
form beire is a genitive plural form of bo (= "both").
So R's phrase, þere beire miȝtes, means the powers of
both of them. Beta has bother(es) while F rewrites the line.
A-geyn deeþ & þe deuyl / þe day for þe nyght he made.F.12.175: F melded two lines into this one. Bx reads as follows:
Ayeins deeþ and þe deuel destruyed hir boþeres myȝtes
Deide and deeþ fordide and day of nyȝt made.
