Jesus spittle mixed with dirt heal the blind man, John 9:6 He spit on the ground made some mud with the saliva and put it on the man’s eyes. Jesus stooped down and wrote on the ground as the scribes and the pharisees brought to him a woman caught in the act of adultery, John 8:3-9.
Jesus uses the clay(ground, dirt) mixed with his spit to heal the blind man because the flesh ( Genesis 2:7) is of the earth and we all understand just as God breath the breath of life into us Jesus spittle became the same. Like being baptized is to be reborn (renew) so was spittle and clay for the blind man eyes so he can see. Jesus focus was on what the eyes sees the heart grieve for, so he want us to keep our eyes on the things of God and his righteousness and salvation for us. The sins in man had the blind man bound. God delivers us out of the dark so we can trust, believe and depend only on his light to guides us through.
When Jesus stooped down and wrote on the ground pertaining to the woman who committed adultery he knew the thought of the Scribes and Pharisee it was the first time Jesus publicly went into the spiritual realm to block out the thoughts and sinful intentions of the enemy. Jesus went into spiritual battle on the ground. Jesus writting on the ground also was to do that which was told to man in Genesis 2:28, be fruitful and mutiply ( his disciples he made fishers of man was his fruits) replenish the earth ( his life and death, replenish) subdue it ( that’s what he was doing when he stooped down and wrote, he was subduing the earth and taking full control) and have dominion over the fish of the sea, over every living things that moves upon the earth.
