David's Prayer - 2 Samuel 7:18-27

So I'm reading in 2 Samuel 7 today, and I come across this prayer of David's, and I noticed something I found a little humorous. I have always thought it was interesting when people use God's name many times during a prayer, and I've always wondered if it's become a filler term...

But then I read this section, and David calls God by name about 9 times in these few verses.

Just thought that was funny.
