Deuteronomy 1:13-17

1:13 Select wise and practical men, those known among your tribes, whom I may appoint as your leaders.” 1:14 You replied to me that what I had said to you was good. 1:15 So I chose as your tribal leaders wise and well-known men, placing them over you as administrators of groups of thousands, hundreds, fifties, and tens, and also as other tribal officials. 1:16 I furthermore admonished your judges at that time that they should pay attention to issues among your fellow citizens and judge fairly, whether between one citizen and another or a citizen and a resident foreigner. 1:17 They must not discriminate in judgment, but hear the lowly and the great alike. Nor should they be intimidated by human beings, for judgment belongs to God. If the matter being adjudicated is too difficult for them, they should bring it before me for a hearing.

Acts 6:3

6:3 But carefully select from among you, brothers, seven men who are well-attested, full of the Spirit and of wisdom, whom we may put in charge of this necessary task.
