'Know' in the Bible

Not many [of you] should become teachers [serving in an official teaching capacity], my brothers and sisters, for you know that we [who are teachers] will be judged by a higher standard [because we have assumed greater accountability and more condemnation if we teach incorrectly].

You adulteresses [disloyal sinners—flirting with the world and breaking your vow to God]! Do you not know that being the world’s friend [that is, loving the things of the world] is being God’s enemy? So whoever chooses to be a friend of the world makes himself an enemy of God.

Yet you do not know [the least thing] about what may happen in your life tomorrow. [What is secure in your life?] You are merely a vapor [like a puff of smoke or a wisp of steam from a cooking pot] that is visible for a little while and then vanishes [into thin air].

You know we call those blessed [happy, spiritually prosperous, favored by God] who were steadfast and endured [difficult circumstances]. You have heard of the patient endurance of Job and you have seen the Lord’s outcome [how He richly blessed Job]. The Lord is full of compassion and is merciful.
