The cross צ
The tsadi צ is like the ayin ע but it touches in the lower right corner, which I call the point of the cross. It symbolizes the reconciliation of Holiness and Love on the cross. It is a symbolism of righteousness. It's name means side and provision. Just as Eve was taken from the side of Adam while he slept/died, so the church was formed from the cross. As Holiness and Love were joined on the cross, provision was made for man to live; hence the lower horizontal from the cross.
The word for tree ets עץ with letters representing sin ע and righteousness ץ. Christ though righteous, bore our sin on the tree/cross.
The word for flourish or blossom is tsuwts צץ, which is the tree of life and the tree of the knowledge of good and evil (the tree of death). The first emphasizes the life given through the cross; the second emphasizes the death. Jesus was called the firstfruit; he was the first living thing on earth, spiritually speaking. He blossomed, flourished and was fruitful through the cross.
The word for "go forth" is tsa צא with a new heaven and earth after the cross. 
Covered wagon, tsab צב is he righteousness of God צ, come into man ב, and working his will in the world (the symbol of wheels and chariots).
The law has a shadow of the kingdom of heaven . The word for shadow is tsel צל which is the teaching ל of the cross צ.
And instruction, tsav צו means to clarify ו the cross צ.
