'Member' in the Bible

Joseph of Arimathea came, a prominent member of the Council, who himself was waiting for the kingdom of God; and he gathered up courage and went in before Pilate, and asked for the body of Jesus.

And a man named Joseph, who was a member of the Council, a good and righteous man

For the body is not one member, but many.

If they were all one member, where would the body be?

whereas our more presentable members have no need of it. But God has so composed the body, giving more abundant honor to that member which lacked,

And if one member suffers, all the members suffer with it; if one member is honored, all the members rejoice with it.
