Some lows and then highs today in our Psalms as David is dealing with his ruthless enemies who are bullying him and then mocking him.  

Psa 13:3-6  Turn and answer me, O LORD my God! Restore the sparkle to my eyes, or I will die.  Don’t let my enemies gloat, saying, “We have defeated him!” Don’t let them rejoice at my downfall.  

That’s definitely something that the wicked like to do, they like to gloat.  Again we look at Proverbs that actually instructs us not to gloat when our enemies stumble, or else the Lord may turn his wrath from them, on to us.  

Regardless of whether or not it is evil to have someone celebrate when we stumble, it still doesn’t feel good, as if defeat isn’t bad enough, defeat with someone doing a touchdown dance in front of you just makes it worse, and that is what David fears at his lowest of low points here.

Given that backdrop, David does what we should do when we are surrounded by the mockers; trust in God:

Psalms 13:4-6 But I trust in your unfailing love. I will rejoice because you have rescued me. I will sing to the LORD because he is good to me.

At the end of the day, when the world is mocking us, and they most certainly will, we look to the Lord to deliver us, and God will see after His children, just like He did with David.
