In English, you’ve seen it written “alleluia” or “hallelujah.” The more accurate way to spell it is Halleluyah, which is actually two Hebrew words joined together: Hallel (Praise) and Yah, which is a shortened form of YHVH, the personal name of the Lord God of Israel.
The hallel-u is a command to ‘you’, but it’s plural — that is, “You all, praise.”
Why do we praise Yah?
Psalm 150:2 “For His mighty deeds; praise Him according to His excellent greatness.”
In other words, we praise Him for everything He is, everything He has done and everything He is going to do.
How do we praise Yah?
Psalm 150:3 says we are to “praise Him with dancing as well as with the sound of the trumpet, harp, lyre, tambourine, strings, pipe, clashing of cymbals, and with our voices”
Those that think heaven is going to be quiet, controlled worship are in for a shocker.
“Let everything that has breath Hallel-u Yah, Hallel-u Yah — Praise the Lord, Praise the Lord.” Praise Him like you mean it!
