Joseph of Arimathaea was a member of the Jewish council (Sanhedrin) at the time of Jesus' ministry. His upright character was seen in his refusal to agree with the Jewish council:
50 Behold, a man named Joseph, who was a member of the council, a good and righteous man 51 (he had not consented to their counsel and deed), from Arimathaea, a city of the Jews, who was also waiting for God’s Kingdom:
Considerable courage was needed for Joseph to ask Pilate for the body of Jesus:
43 Joseph of Arimathaea, a prominent council member who also himself was looking for God’s Kingdom, came. He boldly went in to Pilate, and asked for Jesus’ body. 44 Pilate marvelled if he were already dead; and summoning the centurion, he asked him whether he had been dead long. 45 When he found out from the centurion, he granted the body to Joseph. 46 He bought a linen cloth, and taking him down, wound him in the linen cloth, and laid him in a tomb which had been cut out of a rock. He rolled a stone against the door of the tomb.
Joseph was helped by Nicodemus to bury Jesus:
38 After these things, Joseph of Arimathaea, being a disciple of Jesus, but secretly for fear of the Jews, asked of Pilate that he might take away Jesus’ body. Pilate gave him permission. He came therefore and took away his body. 39 Nicodemus, who at first came to Jesus by night, also came bringing a mixture of myrrh and aloes, about a hundred Roman pounds. 40 So they took Jesus’ body, and bound it in linen cloths with the spices, as the custom of the Jews is to bury. 41 Now in the place where he was crucified there was a garden. In the garden was a new tomb in which no man had ever yet been laid. 42 Then because of the Jews’ Preparation Day (for the tomb was near at hand) they laid Jesus there.
The new tomb, in which Joseph put the body of Jesus, was his own:
57 When evening had come, a rich man from Arimathaea, named Joseph, who himself was also Jesus’ disciple came. 58 This man went to Pilate, and asked for Jesus’ body. Then Pilate commanded the body to be given up. 59 Joseph took the body, and wrapped it in a clean linen cloth, 60 and laid it in his own new tomb, which he had cut out in the rock, and he rolled a great stone against the door of the tomb, and departed.
Joseph’s action fulfilled part of Isaiah's prophecy:
9 They made his grave with the wicked,
and with a rich man in his death,
although he had done no violence,
nor was any deceit in his mouth.
