In Matthew 15:2, the Pharisees criticize Jesus, saying, “Why do thy disciples
transgress the tradition of the elders? for they wash not their hands when they
eat bread.” The Pharisees were not really concerned with physical cleanliness.
The Pharisees wanted Jesus to obey their washing ritual so any heathen
“defilement” would be magically removed.

In verse 15, Peter asks Jesus to explain the parable. He realized there was
deeper meaning than just ritual washing. Jesus explains it this way:

Do not ye yet understand, that whatsoever entereth in at the mouth goeth into
the belly, and is cast out into the draught? But those things which proceed out of
the mouth come forth from the heart; and they defile the man. For out of the
heart proceed evil thoughts, murders, adulteries, fornications, thefts, false
witness, blasphemies: These are the things which defile a man: but to eat with
unwashen hands defileth not a man (Matthew 15:17-20).

This passage is not concerned with dietary laws, but rather the
fruitlessness of ritual washing while the dark heart remains untouched.

Hebrews 10:22 let us draw near to God with a sincere heart in full assurance of
faith, having our hearts sprinkled to cleanse us from a guilty conscience and
having our bodies washed with pure water.
Water played a BIG part throughout the Bible
Gen 1:2
The earth was formless and empty, and darkness covered the deep waters. And
the Spirit of God was hovering over the surface of the waters.

Before there was anything; light, sun or moon, earth, plants, living creatures or anything
else, there was water.

Garden of Eden: All the rivers that went there
Noah: A LOT of water; God cleansing the Earth
Nile River: in Egypt, flows from south to north (upper to lower Egypt). No other river on the
planet flows this way. All others flow from north to south. Egypt is DIFFERENT than Jewish
Moses: set adrift as baby in water, Plaque on Nile, parting of sea, water from rock, Jordan
river, God used the sea for both the deliverance of His people and judgment on the
Egyptian army. Israel is baptized in the Red Sea.
Jonah: the reluctant prophet is saved from stormy sea's by a giant fish, and spit out on dry
Tobias (Tobit): catches giant fish, angel Raphael says to save portions for medicinal
reasons-- to cast away evil spirits (exocism) and to cure blindness
John the Baptist: repenting/baptizing away sins
Jesus: Turning water into wine (his FIRST miracle), calming a storm, preaching from boat,
walking on water. Peter walks on water. Jesus heals a man that was blind from birth. He
uses two forms of water. First he spit on the ground to make mud and then tells the man to
go and take a bath. As he did this his sight returned.
Pontius Pilate: washing his hands from killing an innocent man.

The finale time water is mentioned is in Revelations 22:17

Revelations 22:17 The Spirit and the bride say, “Come.” Let anyone who hears this say,
“Come.” Let anyone who is thirsty come. Let anyone who desires drink freely from the water
of life.

In day five of creation we find in Genesis 1:20 God said "Let the waters bring forth
abundantly the moving creature that have life..." This passage shows us that
life comes
out of the water.

In the natural birth process that is true also. After conception we continue to develop and
grow in what is essentially a sack of water inside the womb.

When a woman is in labor and the baby is about to be born, we wait for that 'water
to break' so that the baby can come forth into life.

Also physical birth (water birth) must come before Spiritual birth as we see in John 3 when
Nicodemus, a ruler of the Jews, is asking questions of Jesus.

John 3: 1-5 Now there was a man of the Pharisees named Nicodemus, a member of the
Jewish ruling council. He came to Jesus at night and said, "Rabbi, we know you are a
teacher who has come from God. For no one could perform the miraculous signs you are
doing if God were not with him." In reply Jesus declared, "I tell you the truth, no one can see
the kingdom of God unless he is born again." "How can a man be born when he is old?"
Nicodemus asked. "Surely he cannot enter a second time into his mother's womb to be
born!" Jesus answered, "I tell you the truth,
no one can enter the kingdom of God
unless he is born of water and the Spirit.
Water in the Bible
Ephesians 5:26 to make her holy, cleansing her by the
washing with water through the word.
Isaiah 55:10-11 As the rain and the snow come down from
heaven, and do not return to it without watering the earth and
making it bud and flourish, so that it yields seed for the sower
and bread for the eater, so is my word that goes out from my
mouth: It will not return to me empty, but will accomplish what I
desire and achieve the purpose for which I sent it.
Hosea 6:3 Let us acknowledge the LORD; let us press on to
acknowledge him. As surely as the sun rises, he will appear;
he will come to us like the winter rains, like the spring rains
that water the earth.
Amos 5:24 But let justice roll on like a river, righteousness like
a never-failing stream!
John 13 shows us Jesus washing His disciples feet. But why only
their feet? That's what Simon Peter asked Jesus as well. Jesus
answered in John 13:10

John 13:10 Jesus answered, "A person who has had a bath needs
only to wash his feet; his whole body is clean. And you are clean...

He was saying that the dirt of the world needed to be

It's true then that, in our life as a believer, we all need to be purified
from the dust and dirt of this world. We do that by reading the Word
of God.

In the dry climate of ancient Greece, water was prized above all.
Giving up water from one's own body, when crying tears for the dead,
was considered a sacrifice. They caught their precious tears in tiny
pitchers or "tear jars." The tears became holy water and could be
used to sprinkle on doorways to keep out evil, or cool the brow of a
sick child

The tear jars were kept unpainted until the owner had experienced
the death of a parent, sibling, child or spouse. After that, the grieving
person decorated the tear jar with intricate designs, and examples of
these can still be seen throughout modem Greece.

Legends of tear bottles, or lachrymatories, also abound in stories of
Egypt and middle eastern societies. In ancient Roman times,
mourners filled small glass vials with tears and placed them in tombs
as symbols of love & respect. In the Old Testament of the Bible, the
notion of collecting tears in a bottle appears in Psalm 56:8.

In the Victorian era, a tear bottle was one of the greatest gifts you
could give someone. It meant that you loved them, that you shared a
grief which brought you together.

This ancient custom symbolizes the transformation that takes place in
people who have grieved deeply.

The Old Testament of the Bible (KJV) references collecting tears in a
bottle in Psalm 56:8 when David prays to God,  “Thou tellest my
wanderings, put thou my tears in Thy bottle; are they not in Thy
Book?” The reference predates the birth of Christ by over 1000 years.

Tear bottles were fairly common in  Roman times, around the time of
Christ, when mourners filled small glass bottles or cups with tears and
placed them in burial tombs as symbols of respect. Sometimes
women were even paid to cry into these vessels, as they walked
along the mourning procession. Those crying the loudest and
producing the most tears received the most compensation, or so the
legend goes. The more anguish and tears produced, the more
important and valued the deceased person was perceived to be.
