'Umpire' in the Bible

“There is no arbitrator between us,Who could lay his hand upon us both [would that there were].

But He said to him, “Man, who appointed Me a judge or an arbitrator over [the two of] you?”

But the man who was injuring his neighbor pushed Moses away, saying, ‘Who appointed you ruler and judge over us?

Let no one defraud you of your prize [your freedom in Christ and your salvation] by insisting on mock humility and the worship of angels, going into detail about visions [he claims] he has seen [to justify his authority], puffed up [in conceit] by his unspiritual mind,

Let the peace of Christ [the inner calm of one who walks daily with Him] be the controlling factor in your hearts [deciding and settling questions that arise]. To this peace indeed you were called as members in one body [of believers]. And be thankful [to God always].
