And if he refuses to listen to them [i.e., the witnesses], explain the [whole] matter to the church [i.e., probably a specially called meeting of mature Christians to resolve the matter].

He [then] went away a second time and prayed, "My Father, if this [cup of suffering] cannot pass away unless I drink it [i.e., experience the suffering], [then] let what You want be done."
