The 5th letter Ha (pronounced hey) is a picture of a human raising their hands in praise to the Lord (Many jewish songs end with the raising of the hands while saying hey). A newborn, 34 weeks at birth to 5 months, positions themselves this way during the moro reflex, and babies sleep in this manner. Ha, a breath that has the sound of H, is a cry of praise for the Breath of Life (spiritual life on earth) given to all living things on earth. On the 5th day, fish were made for the blue sea and birds were made for the blue sky, blue being the 5th color. The sky and the birds within it represent the spiritual realm, while the water and the fish within it represent what is a part of both the spiritual realm and the physical earthly realm. A human who lives on earth within the physical realm but has been adopted into the kingdom of Heaven within the spiritual realm is an example of the fish's representation.  In order for humans to be adopted into the kingdom of God to become fruitful themselves, they must make Yeshua, the First Fruit, their Lord and God and believe Yeshua died on a tree for their sins and was resurrected from the dead to give them resurrection (Co 15:20, 21, 22, 23; Ro 10:9). Yeshua's resurrection occurred after the shabbat (shabbat = sabbath = saturday) on First Fruits (First Fruits=Resurrection Sunday=easter Sunday) at the beginning of 5000 years after creation. (Lev 23:6, 7, 8, 9, 10, 11, these verses refer to First Fruits/first grain). This is why fruit from the fruit tree is regarded as forbidden the first three years, is holy the fourth year and to be tithed (See Dalet), and can be eaten in the 5th year (Lev 19:23, 24, 25). So even the trees lift their branches in praise to the Lord, Hey!
