Adjective aposynagōgos (out of the synagogue) in the Gospels-Acts

(Translation from NRSV)

John

9: 22His parents said this because they were afraid of the Jews; for the Jews had already agreed that anyone who confessed Jesus to be the Messiah would be put out of the synagogue (aposynagōgos).
12: 42Nevertheless many, even of the authorities, believed in him. But because of the Pharisees they did not confess it, for fear that they would be put out of the synagogue (aposynagōgos);
16: 2They will put you out of the synagogues (aposynagōgos). Indeed, an hour is coming when those who kill you will think that by doing so they are offering worship to God.
