'Need' in the Bible

Therefore let us approach with confidence to the throne of grace, in order that we may receive mercy and find grace to help in time of need.

For indeed, [although you] ought to be teachers {by this time}, you have need of someone to teach you again the beginning elements of the oracles of God, and {you have need of} milk, not solid food.

Thus if perfection was through the Levitical priesthood, for on the basis of it the people received the law, what further need [is there] for another priest to arise according to the order of Melchizedek and not said to be according to the order of Aaron?

who does not {need every day} like the former high priests to offer up sacrifices for his own sins [and] then for the [sins] of the people, because he did this once for all [when he] offered up himself.

For you have need of endurance, in order that [after you] have done the will of God, you may receive what was promised.
