'Tribe' in the Bible

The thing pleased me and I took twelve of your men, one man for each tribe.

At that time the Lord set apart the tribe of Levi to carry the ark of the covenant of the Lord, to stand before the Lord to serve Him and to bless in His name until this day.

“The Levitical priests, the whole tribe of Levi, shall have no portion or inheritance with Israel; they shall eat the Lord’s offerings by fire and His portion.

so that there will not be among you a man or woman, or family or tribe, whose heart turns away today from the Lord our God, to go and serve the gods of those nations; that there will not be among you a root bearing poisonous fruit and wormwood.
