In Numbers, responsibilities and tasks are defined according to tribe. In Hebrews, Paul reminds us to strive for peace with all men and to guard against certain weeds (bitterness, immorality and vulgarity) springing up in our lives.
Therefore let us also, seeing we are surrounded by so great a cloud of witnesses, lay aside every weight and the sin which so easily entangles us, and let us run with patience the race that is set before us,
looking to Jesus, the author and perfecter of faith, who for the joy that was set before him endured the cross, despising its shame, and has sat down at the right hand of the throne of God.
For consider him who has endured such contradiction of sinners against himself, that you don't grow weary, fainting in your souls.
You have not yet resisted to blood, striving against sin;
and you have forgotten the exhortation which reasons with you as with children, "My son, don't take lightly the chastening of the Lord, nor faint when you are reproved by him;
For whom the Lord loves, he chastens, and scourges every son whom he receives."
It is for discipline that you endure. God deals with you as with children, for what son is there whom his father doesn't discipline?
Follow after peace with all men, and the sanctification without which no man will see the Lord,
looking carefully lest there be any man who falls short of the grace of God; lest any root of bitterness springing up trouble you, and many be defiled by it;
lest there be any sexually immoral person, or profane person, like Esau, who sold his birthright for one meal.
Therefore, receiving a Kingdom that can't be shaken, let us have grace, through which we serve God acceptably, with reverence and awe,
