Psalm 52:7-8 King James Version (KJV) , 7 Lo, this is the man that made not God his strength; but trusted in the abundance of his riches, and strengthened himself in his wickedness. 8 But I am like a green olive tree in the house of God: I trust in the mercy of God for ever and ever.
The olive tree has many symbolic meanings. In the text the Hebrew word is zayith ( רַעֲנָן ׳ז ) meaning fresh, (thriving) olive-tree (simile of prosperity).
When an individual puts their just in their our strength and riches, they will be like the certain rich man in Luke 12:16-20 (KJV);
16 And he spake a parable unto them, saying, The ground of a certain rich man brought forth plentifully: 17 And he thought within himself, saying, What shall I do, because I have no room where to bestow my fruits? 18 And he said, This will I do: I will pull down my barns, and build greater; and there will I bestow all my fruits and my goods. 19 And I will say to my soul, Soul, thou hast much goods laid up for many years; take thine ease, eat, drink, and be merry. 20 But God said unto him, Thou fool, this night thy soul shall be required of thee: then whose shall those things be, which thou hast provided?
The Olive tree also symbolizes the tree of hope, the tree of light and the tree of wealth.
The tree of hope: In the Old Testament a dove returns with an olive branch in the ark, in order to announce the end of flood and bring hope to people.
The tree of light: The olive oil was used as lighting oil and thus it was considered to be source of light.
The tree of wealth: For many families the olive trees and their products represent the main source of income.
When we put our trust in God we are thriving and prosperous in the house of God. This is exactly what GOD wants for his people.
