Easter
originally a Saxon word (Eostre), denoting a goddess of the Saxons, in honour of whom sacrifices were offered about the time of the Passover. Hence the name came to be given to the festival of the Resurrection of Christ, which occured at the time of the Passover. In the early English versions this word was frequently used as the translation of the Greek pascha (the Passover). When the Authorized Version (1611) was formed, the word "passover" was used in all passages in which this word pascha occurred, except in Act 12:4. In the Revised Version the proper word, "passover," is always used.
