Like so many common verbs, the meaning of "know" in the Bible is varied and dependent on context. And in some cases -- when it is connected to ideas or objects -- its spiritual meaning and natural meaning are essentially the same. When the Bible talks about people knowing each other and especially when it talks about the Lord knowing people, the meaning has more to do with the states of love within people than it does with any factual knowledge. This makes sense if you think about it. When we really "know" somebody, what we mean is that we know what kind of person they are, what their motivations are, what they love, what they hate, what makes them tick. Those things are far more important than knowing their parents' names, where they were born or what year they graduated from school. Most often then, especially applied to people, "knowing" has to do with the perceptions we have about other people's loves and the conjunction that can exist between those with similar loves, not just a collection of facts.

10155. 'And they will recognize that I am Jehovah their God' means perception that the Lord is the source of all good and all truth. This is clear from the meaning of 'recognizing' as understanding, believing, and perceiving, dealt with below. The reason why perceiving that the Lord is the source of all good and all truth is meant is that the names Jehovah and God are used, and the Lord is called Jehovah by virtue of good and God by virtue of truth, see 2586, 2769, 2807, 2822, 3921, 4287, 4402, 7010, 9167.

The reason why 'recognizing' means understanding, believing, and perceiving is that the word is used in reference both to the human power of understanding and to the power of will. When used in reference solely to the power of understanding it means understanding; when used in reference to the understanding and at the same time the will it means believing; and when used in reference solely to the will it means perceiving. With those therefore who merely know of something and as a result think about it, recognizing implies understanding. But with those who possess faith, recognizing implies believing, and with those who have love, recognizing implies perceiving.

[2] When however recognizing is coupled with understanding, seeing, or believing, 'recognizing' means perceiving; for understanding, seeing, and believing are connected with the understanding, consequently with truth, whereas perceiving is connected with the will, consequently with good, as in John,

Peter said, We have believed and recognized that You are the Christ, the Son of the living God. John 6:69.

In the same gospel,

Jesus said, Believe the works, that you may recognize and believe that the Father is in Me, and I in the Father. John 10:38.

In the same gospel,

Jesus said, If you recognize Me you recognize My Father, and from now on you recognize Him and have seen Him. John 14:7.

In the same gospel,

The Spirit of truth will be sent, whom the world cannot receive, because it neither sees Him nor recognizes Him. But you recognize Him, because He remains with you and will be in you. John 14:16-17.

In Mark,

Jesus spoke in parables, so that seeing they may see and not recognize. Mark 4:11-12.

In Jeremiah,

... that you may recognize and see that it is evil and bitter to depart from Jehovah your God. Jeremiah 2:19.

In the same prophet,

Let him who glories glory in this, to understand and to recognize Me, that I am Jehovah. Jeremiah 9:24.

In Hosea,

I will betroth you to Me in faith, and you will recognize Jehovah. Hosea 2:20.

[3] In these places 'recognizing' means perceiving, and perceiving comes about as a result of good, whereas understanding and seeing come about as a result of truth. For inwardly within themselves those in whom good or love is predominant perceive that something is so, whereas within themselves those in whom truth or faith is predominant see that it is such. Therefore perception that something is so exists among those who are in the Lord's celestial kingdom, but belief that it is so among those who are in the Lord's spiritual kingdom, see the places referred to in 9277, and what has been stated in 9992, 9995, 10105. And what perception is, see 125, 371, 483, 495, 503, 521, 536, 597, 607, 1121, 1384, 1387, 1398, 1442, 1919, 2144, 2515, 2831, 3528, 5121, 5145, 5227, 7680, 7977, 8780.

[4] In addition, since the proper meaning of 'recognizing' is perceiving as a result of good, reference is made in Deuteronomy 8:5 to recognizing from the heart; for 'from the heart' means from the good of love, 3883-3896, 7542, 9050, 9300, 9495. Therefore also doing good is referred to as recognizing Jehovah, Jeremiah 22:16.

From all this it is evident that 'they will recognize that I am Jehovah their God' means perception that the Lord is the source of all goodness and truth.
