'Bible' is the name given to the set of canonical books for Jews (Old Testament) and Christians (Old and New Testaments). By extension it is said of a fundamental text, the most important on a subject . The name is Latin , taken from the Greek expression 964; 945; 946; 953; 946; 955; 953; 945; 964; 945; 945; 947; 953; 945; ( ta biblía ta ayia "the holy books" ) . Actually Bible in Greek is in plural , but as it ends in /a/ the Spanish takes it as feminine and singular .
