Shmuel Bais 23:3-4

The Elohei Yisroel said, the Tzur Yisroel spoke to me, He that ruleth over adam, Tzaddik, ruling in the yirat Elohim. And He shall be as the ohr of the boker, when the shemesh riseth, even a morning without clouds; as the tender deshe (grass) springing out of ha'aretz by clear shining after matar (rain).
