Meaning and Derivation: Qanna is translated as "jealous," "zealous," or "envy." The fundamental meaning relates to a marriage relationship. God is depicted as Israel's husband; He is a jealous God, wanting all our praise for Himself and no one else. [BlueLetterBible]

Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me.
Exodus 20:5

Back in the day when I was a young little lady I had a serious jealousy problem when it came the most important person to me on this globe to me. My momma. She, being super loving, kind, and overall awesome welcomed my friends with open arms. Without fail, every day after school we would bounce off of the school bus to find a warm embrace and homemade treats waiting for us. Under most circumstances her affection towards other children did not bother me (as I now know she was doing an amazing job of showing  Christ's love), but on a few occasions it did. One she and I both now laugh about now, was when she invited a friend of mine to go to the mall with us. For whatever reason I wanted this to be just a mom and I outing, and lost it. So my mom did what was appropriate, left me at home wiping my nose to be watched by my diddy while she and Sabrina went out and shopped til they dropped. 

  

While the jealousness that I portrayed came from a human, mildly selfish state of mind, how much more so can the One who created us care for our attention when all of His being is rooted in goodness and love? He wants, He desires, He hopes that we (His creation) will choose Him, worship Him, commune with Him. He has all the right to be known as El Qanna. He is the reason we exist, He is the reason we breathe, He is the reason those who accept His son as savior will be reunited with Him.  

Do not worship any other god, for the LORD, whose name is Jealous, is a jealous God.

For the LORD thy God is a consuming fire, even a jealous God.
