"Behold, the days are coming," says the LORD, "that I will raise to David a Branch of righteousness; a King shall reign and prosper, and execute judgment and righteousness in the earth.
In His days Judah will be saved, and Israel will dwell safely.
Now this is His name by which He will be called: The LORD our Righteousness, Yahweh Tsidkenu"

The Hebrew word for righteousness, speaks of that which is altogether right and just.
It also refers to prosperity.
Righteousness is God's way of doing and being right.
It is His 'righteousness'.
When we walk in His righteousness, we experience His blessings and prosperity.
Psalm 112 describes the blessing and prosperity of those who are righteous.
Jesus is the Branch of David, the King who reigns and prospers. He is our righteousness.
"For He [God] made Him [Jesus] who knew no sin to be sin for us, that we might become the righteousness of God in Him."
2 Corinthians 5:21
We are eligible for every blessing and benefit that belongs to the righteous.
Sickness and disease belong to the curse, but healing and wholeness belong to the blessing and the blessing belongs to us the righteous.
