The first reference to a kiss in the Bible may have come when God gave consciousness to the first human being. When Adam was created it states, "Then the Lord God formed man of the dust of the ground, and breathed into his nostrils the breath of life . . ." (Genesis 2:7, HBFV throughout).
The first literal use of the word 'kiss" is in Genesis 27:26. It occurred when Isaac requested that Esau, who was actually Jacob in disguise, give him one before he gave the birthright blessing.
Tradition
Jewish tradition believes, based on Deuteronomy 34:5, that the death of Moses was accomplished through a kiss given by God. It also states that when a person died they were given this show of affection before their eyes were closed and the body prepared for burial.
The religious tradition of the Jews additionally infers, based upon a unique rabbinical interpretation of Psalm 62:12, that there were 903 ways of dying. The best and gentlest of these, compared to drawing a hair out of milk, was called "death by a kiss."
Old Testament kisses include Jacob using them as a symbol of affection toward his future wife Rachel (Genesis 29:11). Despite earlier chicanery, Esau greeted his brother with this show of love (Genesis 33:4). Joseph welcomed his brothers, who had sold him as a slave because they envied him, with this sign of forgiveness (Genesis 45:14 - 15).
Israel gave this sign of affection to the sons of Joseph before placing the family name upon them (Genesis 48:8 - 10). This sign of affection was also given by Joseph to Jacob, just before he died, as a sign of his love (Genesis 49:33 - 50:1).
New Testament Examples
The New Testament records that Christians gave each other a kiss as a sign of greeting and affection (see Romans 16:16, 1Corinthians 16:20, 2Corinthians 13:12, 1Thessalonians 5:26, 1Peter 5:14). Although there has been much speculation over the meaning of this Biblical practice, it certainly was not sexual in nature.
The Kiss of Death
The most famous kiss of the Bible, one that represented death, is the one Judas gave to Jesus. It was given in the Garden of Gethsemane, the place where Jesus and the disciples went after they finished celebrating their last Passover together.
Now the one who was betraying Him (Judas Iscariot) gave them a sign, saying, 'Whomever I shall kiss, He is the One. Arrest Him!' (Matthew 26:48).
This type of showing of respect were not unusual during the time of Christ. In the first century, it was customary for a student to greet a teacher in such a manner. Ironically, Judas' feigned token of affection precipitated Jesus' last miracle before his death when he had to heal a servant's ear impulsively chopped off in an attempt to protect him (Luke 22:49 - 51).
