k 16:1-2
"And when the Sabbath was Past, Mary Magdalene, and Mary the mother of James, and Salome, had brought sweet spices, that they might come and anoint Him.
and very early in the morning the first of the Sabbath, they came unto the sepulchre at the rising of the sun.
Once again we see the language of one Sabbath being past (saturday), and they came to the tomb early in the morning of the FIRST of the Sabbaths (sunday). Very plain language that God is telling us of a new Sabbath day. Again, in your translation one of the words may read 'Week,' but both of the words are the 'identical' word Sabbaths [sabbaton]. God is alerting us that the old testament Sabbath is past, and with the resurrection of Christ, it's the start of the FIRST of the Sabbaths. What some theologians don't fully comprehend is that God knows what He is doing and has inspired to be said exactly what He wanted said. Every Word of God is deliberate, immutable, intentional, purposeful, and meaningful. Every jot and every tittle.
