'Trifling' in the Bible

for it [is] not a trifling matter among you, but it [is] your life, and through this word {you will live long in the land} that you [are about] to cross the Jordan [to get] there to take possession of it."

"Now therefore, our God, the great, mighty, and awesome God, who keeps the covenant and gracious love, don't let all of the difficulties seem trifling to you, all of hardships that have come upon us, upon our kings, upon our leaders, upon our priests, upon our prophets, upon our ancestors, and upon all of your people from the time of the kings of Assyria until this day.

But have nothing to do with foolish and ignorant speculations [useless disputes over unedifying, stupid controversies], since you know that they produce strife and give birth to quarrels.
