"Alleluia" or "Hallelujah"?

In the past several weeks I've been asked by several folks what is the difference between "Alleluia" and "Hallelujah". They are both an expression of praise to God. Hallelujah comes from the Hebrew (used in Psalms) which means "Praise Yahweh". It's also found in the New Testament book of Revelation. Alleluia is simply the Greek or Latin form of the same word. They can be used interchangeably. But the important thing is, no matter what form you choose to use, DO praise God for all that we have been given.
