This rare kanji has no clear standalone meaning. Treat its meaning as uncertain.
The exact historical development of 倗 is uncertain. It visually combines 亻 (person) with 朋, but the original semantic and phonetic roles are unclear.
A person 亻 beside 朋 (a pair of moons or friends) might suggest a helper or companion, but the meaning is not confirmed.
For ホウ, imagine a person 亻 calling out 'Ho!' to a friend 朋 for help: 'Ho!' -> ホウ.
