Robertson's Word Pictures (NT)
The day of the Preparation (hmera paraskeuhv). The technical Jewish phrase for the day before the sabbath for which see discussion on Matthew 27:62.
Drew on (epefwsken). Imperfect active, began to dawn or give light. However, it was sundown, not sunrise when the Jewish sabbath (twenty-four-hour day) began. The confusion is to us, not to the Jews or the readers of the Greek New Testament. Luke is not speaking of the twelve-hour day which began with sunrise, but the twenty-four-hour day which began with sunset.
