'Kingdom of God' in the Bible

Aristarchus my fellow-prisoner salutes you, and Mark the nephew of Barnabas,??oncerning whom you received commandments, if he comes to you receive him,??11 and Jesus called Justus, who are of the circumcision; these are the only co-laborers for the kingdom of God who have been a comfort to me.

And Jesus, which is called Justus, who are of the circumcision. These only are my fellowworkers unto the kingdom of God, which have been a comfort unto me.
