If any of us, especially worship leaders, were wondering about where to find some answers on the topic of worship in the Bible start at Psalm 92:1-3.

"It is good to praise the LORD and make music to your name, O Most High, to proclaim your love in the morning and your faithfulness at night, to the music of the ten-stringed lyre and the melody of the harp."

What? And who and a little bit of why? 
"It is good" for us to worship the LORD and not only is it "good" to worship Him, but worship is actually already broken down in this verse into "praise" (Hebrew - Yadah) meaning to give thanks, extol, make a public confession,or make an admission AND "make music" (Hebrew - Zamar) meaning to sing, sing praises. 

Another why? 
Of course all of these praises and making music is to the glory of His name.  Here, "O Most High" is the name that is selected and lifted up.  But in each one of our lives we can pick a different name we know God by and "praise" and/or "make music" to that name (Provider, Great Physician, Shepherd, Healer, Defender, etc...).

Another what and when?  The passage offers specific subjects about what to "praise" and "make music" to the LORD for , especially in verse two ("love" and "faithfulness").  We are even told the time (when) to worship - "proclaim [His] love in the morning and [His] faithfulness at night." 

With what?  Voices to sing, naturally.  However, the Scripture reveals the selection of instruments to be used - "ten-stringed lyre and...harp."  Can you imagine a modern day worship service where just these instruments or the instruments of Moses's or David's day were used?

There are many other Scripture passages in the Bible which speak to the subject of worship, but this one was only three verses and loaded.  It was also the first one about worship I've come across in my third reading of the whole Bible that really struck me so.
