In John 21:15-17, when Peter responds to Jesus, saying, "You know all things; You know that I love You," the Greek word translated as "know" in his previous answers is *eido* (G1492). This term carries the sense of seeing in a figurative way, implying understanding, comprehending, and perceiving. Each time Peter uses *eido*, it reflects his acknowledgment that Jesus perceives and understands the depth of his feelings, highlighting a distinction in the nature of knowledge between mere perception and experiential understanding in his responses to Jesus' questions about love.

In John 7, the concept of knowing is explored through the Greek word *eido* (G1492), which appears in verse 27. Here, the crowd expresses their belief that they know Jesus' origins, stating, "However, we know where this Man is from." This usage of *eido* reflects a sense of mental or perceived knowledge, a certainty based on information they have heard or accepted as true about Jesus being from Nazareth. They contrast this with the expectation that when the Christ comes, no one will know His origins, implying a lack of experiential or observable knowledge about the true Messiah. Jesus responds to this misunderstanding by publicly declaring that while they think they know Him and His origins, they do not know the One who sent Him, God the Father. His statement challenges their perceived knowledge, asserting that true understanding comes from recognizing His divine source, which they fail to grasp. This exchange during the Feast of Tabernacles underscores a key theme of the chapter: the difference between superficial knowledge and the deeper truth of divine origin and relationship.

In the New Testament, one of the words for "know" is *eido* (G1492), which means to have regard for someone, to cherish, and to pay attention to. An example of this usage appears in I Thessalonians 5:12, where it urges recognizing and knowing those who labor among the believers, referring to the ministry. This implies having a relationship with them, cherishing their role, and paying attention to their teachings and actions.
