What is the meaning of God's omni-powers? It is a common understanding among Christians I know that God has these four attributes: 


Omnipresence
Omniscience
Omnipotence
Omnibenevolence


A grammatical interpretation would explain them as unlimited or maybe absolute, but I'm interested in the biblical approach to this matter. What is the meaning attributed to each of these "powers" in the Bible?
I'm sure there are other references, but for example:

Omnipresence: Psalm 139:7-12 describes God being everywhere.

Omnipotence: I can't think of a Bible verse that says, "God is omnipotent". But Deut 4:37 (and many similar verses) talk about God's "might power". Gen 17:1 and others refer to God as "Almighty". Job 11:7b "Can you find out the limits of the Almighty?"

Omnibenevolence: Luke 18:19 "So Jesus said to him, 'Why do you call Me good? No one is good but One, that is, God.'"

I can't think of a verse for omniscience off the top of my head.

Omniscience: OT reference Psalm 69:5 - if He knows all our sins, He knows it all
and NT reference 1st John 3:20 comes right out and says that "...God is greater than our heart, and knows all things."
