“Now when forty years had passed, there appeared to him in the desert near Mount Sinai an angel (angelos | ἄγγελος | nom sg masc) in the flame of a burning bush.
She saw two angels (angelous | ἀγγέλους | acc pl masc) in white sitting there, one at the head and the other at the feet of the place where the body of Jesus had been lying.
The crowd that was standing there and had heard the voice said that it was thunder; others said, “An angel (angelos | ἄγγελος | nom sg masc) has spoken to him.”
Then he said to him, “I tell you the solemn truth: you will see heaven standing open and the angels (angelous | ἀγγέλους | acc pl masc) of God ascending and descending on the Son of Man.”
and not finding his body, they came back saying that they had even seen a vision of angels (angelōn | ἀγγέλων | gen pl masc) who said that he was alive.
