Some early Christians followed the practice of taking vows ( Paul, e.g., taking the temporary vow of a Nazirite, Acts 21. 22–6), although Jesus had warned against letting a dedication of something to God through qorban take precedence over more fundamental obligations (Mark 7. 11). Vows came to be understood as a social act through which a person donates himself or herself to another (marriage vows), or to God in a religious community.
For examples of vows in other religions, see BODHISATTVA VOW; FIVE GREAT VOWS (among Jains); SHIGUSEIGAN (the four great vows in Zen); VRATA;
