Genesis 21 and Isaiah 21 giving water and bread:

Genesis 21:14 (KJV) 14 And Abraham rose up early in the morning, and took bread, and a bottle of water, and gave [it] unto Hagar, putting [it] on her shoulder, and the child, and sent her away: and she departed, and wandered in the wilderness of Beersheba.

Isaiah 21:14 (KJV) 14 The inhabitants of the land of Tema brought water to him that was thirsty, they prevented with their bread him that fled.

Then numbers 21 people complained in the desert that there was no water and moses hit the rock and then when entering the amorite territory they don't even want to drink their water but simply to pass by. Imagine coming from a desert and not be thirsty? Showing our lives dependent on God.

Spoke 21 (the bible has 66 books divided in 3 cycles of 22 books as the hebrew alphabet has 22 letters therefore John falls on spoke 21 of the 2nd cycle more on this https://www.facebook.com/groups/354431877994141/) John:

John 4:10 (KJV) 10 Jesus answered and said unto her, If thou knewest the gift of God, and who it is that saith to thee, Give me to drink; thou wouldest have asked of him, and he would have given thee living water.

John 7:38 (KJV)
He that believeth on me, as the scripture hath said, out of his belly shall flow rivers of living water.

Revelation 21:6 (KJV) 6 And he said unto me, It is done. I am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.
