Psalm 92:12-15 says:
12 The righteous shall flourish like the palm tree: he shall grow like a cedar in Lebanon.
13 Those that be planted in the house of the Lord shall flourish in the courts of our God.
14 They shall still bring forth fruit in old age; they shall be fat and flourishing;
15 To shew that the Lord is upright: he is my rock, and there is no unrighteousness in him.
