'Know' in the Bible

‘I know your deeds and your toil, and your patient endurance, and that you cannot tolerate those who are evil, and have tested and critically appraised those who call themselves apostles (special messengers, personally chosen representatives, of Christ), and [in fact] are not, and have found them to be liars and impostors;

and [I know that] you [who believe] are enduring patiently and are bearing up for My name’s sake, and that you have not grown weary [of being faithful to the truth].

‘I know your suffering and your poverty (but you are rich), and how you are blasphemed and slandered by those who say they are Jews and are not, but are a synagogue of Satan [they are Jews only by blood, and do not believe and truly honor the God whom they claim to worship].

Keep and obey them, and repent [change your sinful way of thinking, and demonstrate your repentance with new behavior that proves a conscious decision to turn away from sin]. So then, if you do not wake up, I will come like a thief, and you will not know at what hour I will come to you.

‘I know your deeds. See, I have set before you an open door which no one is able to shut, for you have a little power, and have kept My word, and have not renounced or denied My name.

‘I know your deeds, that you are neither cold (invigorating, refreshing) nor hot (healing, therapeutic); I wish that you were cold or hot.

I said to him, “My lord, you know [the answer].” And he said to me, “These are the people who come out of the great tribulation (persecution), and they have washed their robes and made them white in the blood of the Lamb [because of His atoning sacrifice].
