“But when they went in,
They did not find
εἰσελθοῦσαι δὲ οὐχ εὗρον τὸ σῶμα τοῦ Κυρίου Ἰησοῦ.
Only Luke uniquely said that when the women went into the tomb (εἰσελθοῦσαι δὲ), they did not find (δὲ οὐχ εὗρον) the body (τὸ σῶμα) of Jesus, the Lord (τοῦ Κυρίου Ἰησοῦ). Luke was the only canonical gospel that explicitly said that the body of Jesus was gone. It became obvious, but these women of Galilee noticed it before anything else happened. What would you do if the body you were visiting was gone?
