For as yet they did not know

1 Now the first day of the week Mary Magdalene went to the tomb early, while it was still dark, and saw that the stone had been taken away from the tomb. 2 Then she ran and came to Simon Peter, and to the other disciple, whom Jesus loved, and said to them, “They have taken away the Lord out of the tomb, and we do not know where they have laid Him.
3 Peter therefore went out, and the other disciple, and were going to the tomb. 4 So they both ran together, and the other disciple outran Peter and came to the tomb first. 5 And he, stooping down and looking in, saw the linen cloths lying there; yet he did not go in. 6 Then Simon Peter came, following him, and went into the tomb; and he saw the linen cloths lying there, 7 and the handkerchief that had been around His head, not lying with the linen cloths, but folded together in a place by itself. 8 Then the other disciple, who came to the tomb first, went in also; and he saw and believed. 9 For as yet they did not know the Scripture, that He must rise again from the dead. 10 Then the disciples went away again to their own homes.
