Joanna (Greek: Ἰωάννα) was a wife of Chuza. Her husband was a steward of Herod. Jesus healed her, and she helped provide for Jesus and his ministry. She is mentioned, along with Mary Magdalene and Susanna, in Luke 8.
She was one of the women bringing spices and ointments to Jesus' tomb in order to anoint His body. When they arrived, the stone in front of the tomb's entrance was rolled away, and Jesus' body was not in the tomb. They were confused, and two angels suddenly appeared. The women were frightened and bowed their heads, and the angels asked the women why they were looking for the living among the dead. The angels told the women that Jesus had risen from the dead, as prophesied.
But on the first day of the week, at early dawn, the women went to the tomb bringing the spices which they had prepared [to finish anointing the body]. And they found the [large, circular] stone rolled back from the tomb, but when they went inside, they did not find the body of the Lord Jesus. While they were perplexed and wondering about this, suddenly, two men in dazzling clothing stood near them; and as the women were terrified and were bowing their faces to the ground, the men said to them,Why are you looking for the living One among the dead? He is not here, but has risen. Remember how He told you, while He was still in Galilee, saying that the Son of Man must be handed over to sinful men, and be crucified, and on the third day rise [from death to life].And they remembered His words, and after returning from the tomb, they reported all these things to the eleven [apostles] and to all the rest. Now they were Mary Magdalene and Joanna [the wife of Chuza, Herod’s steward] and Mary the mother of James; also the other women with them were telling these things to the apostles. But their report seemed to them like idle talk and nonsense, and they would not believe them.— Luke 24:1–24:11 (AMP)
Peter went to the tomb and found that Jesus' body was not there. The Apostles would later believe in what the women said after the resurrected Jesus appeared before them.
