"Hallelujah" - the Hebrew "hil¬lel" - "praise Jehovah," "praise Jah!" - Jehovah. (Acts 19:1,3,4,6).
It was used as an exclamation of joy, thanksgiving, and praise to God.
The man should give glory to God alone - full obedience, veneration, reverence and immense gratitude. The true praise of the Most High is the recognition of His spiritual and moral laws of life and their faithful fulfillment. The evidence of visible manifestation of glory to the Creator is the fulfillment of His Commandments and their preaching among the nations. A righteous person becomes an example of a true, righteous life, showing true glory to God. A righteous life is a true praise to God.
