'Perfect' in the Bible

Perfect justice shalt thou follow, that thou mayest live, and possess the land that Jehovah thy God giveth thee.

Thou shalt be perfect with Jehovah thy God.

A perfect and just weight shalt thou have; a perfect and just ephah shalt thou have; that thy days may be prolonged in the land that Jehovah thy God giveth thee.

He is the Rock, his work is perfect, For all his ways are righteousness; A God of faithfulness without deceit, Just and right is he.
