There were guards on Sunday.
And how would you know that?
Matthew 27:60 And laid it in his own new tomb, which he had hewn out in the rock: and he rolled a great stone to the door of the sepulchre, and departed.
Matthew 28:1 But late in the week, at the dawning into the first day of the week, Mary Magdalene and the other Mary came to see the tomb.
2 And behold, a great earthquake occurred! For coming down from Heaven, and coming up, an angel of the Lord rolled back the stone from the door and was sitting on it.
3 His countenance was like lightning, and his clothing white as snow.
4 And the keepers shook for fear of him and became like dead men.
5 And the angel answered and said to the women, Do not fear, for I know that you seek Jesus who was crucified.
6 He is not here, for He has risen, as He said. Come, see the place where the Lord lay.
7 And go quickly and tell His disciples that He has risen from the dead. And, behold, He goes before you into Galilee. There you shall see Him. Lo, I have told you.
8 And they quickly departed from the tomb with fear and great joy, and ran to bring His disciples word.
9 But as they were going to report to His disciples, behold, Jesus also met them, saying, Hail! And they came and held Him by the feet and worshiped Him.
10 Then Jesus said to them, Do not be afraid; go tell My brothers that they should go into Galilee, and there they will see Me.
Mark 15:46 And he bought fine linen, and took him down, and wrapped him in the linen, and laid him in a sepulchre which was hewn out of a rock,

hey saw that the stone was rolled away: for it was very great.
