Lastly, we have the night of the Sabbath and the dawn of the Lord's Day, as noted in Matthew: “on one Sabbath, at daybreak,” which indicates that the morning is included in the count for the entire day—therefore representing the third twenty-four-hour period.
Alternatively, we can account for the three days differently: on Friday, the Lord breathed His last, which is one day; on Saturday, He lay in the tomb, making it another day; and during the night leading to the Lord's Day, He arose, which, from His perspective, counts as a third day. Consider this: even regarding the deceased, if one one dies at the tenth hour and another at the first hour of the same day, they are said to have died on the same day.
Let me provide another method for calculating the three days and three nights. On Thursday evening, the Lord shared a meal with His disciples, saying, “Receive, eat My body.” Since He possessed the authority to lay down His life at will, it is evident that He willingly surrendered Himself while teaching His disciples about His body, as no one consumes anything that hasn’t been pierced first. Ponder this: in the evening, He instructed about His body, and that night until the sixth hour of Friday constitutes one complete twenty-four-hour period. From the sixth hour to the ninth, there was darkness, followed by light until evening, accounting for a second twenty-four hours. Again, the night after His crucifixion and the day of the Sabbath form the third twenty-four hours. The Lord then rose on the Sabbath night, totaling three full twenty-four-hour spans.
Concerning the angel, Matthew describes him as sitting on the stone, while Mark notes that after rolling it away, he sat inside the tomb on the right side. Are these accounts contradictory? Not at all! Evidently, the angel first appeared perched on the stone, and upon the women’s arrival, he guided them and then took his place inside the tomb on the right side. He addressed the women, saying, “Do not be afraid,” indicating that the guards should indeed be fearful, but that the disciples of the Lord need not fear. After calming their fears, he proclaimed the joyous news of the resurrection, for he needed to dispel fear before declaring the glad tidings. He proudly speaks of the Lord's crucifixion, for he sees the cross as a victorious standard, which has brought us all blessings.
