It was now the next day after the Sabbath and the second day of the Feast of Unleavened Bread. The women have just this one work day to gather the spices needed to anoint Jesus body before the weekly Sabbath; if you follow the biblical calendar rather than our calendar, this makes more sense. This would have been the start of Jesus second day in the grave. They had witnessed His horrific death, rested in acknowledgment of the Passover, and the festival had begun, all while trying to process what had just happened. They must have been so overwhelmed with grief. They had to go on with life and do what was necessary to meet their obligations and their desire to honor Jesus. We all have dark days, it's just part of life. During these times, we must remember that we are not alone and must give ourselves over to Jesus and allow Him to carry us through these tough times.
When the Sabbath was past, Mary Magdalene, Mary the mother of James, and Salome bought spices, so that they might go and anoint him. Mark 16:1
Likewise the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words. Romans 8:26
