This Psalm is full of confessional truth. If you look at the back of the Westminster Confession of Faith scripture index. We find confessions on Decalogue, assurance of faith and on the Lord's supper.

It is confessional also because the psalmist confess what he see first and then profess his faith in the second part.

Do you have a necklace? necklace is an accessory for women mostly. A decoration.

But we all have decoration. Do we? Psalmist saw the wicked has PRIDE as his decoration. The Lord also promised us that our salvation and humility is our decoration in Ps. 149.

What decorated you? You knowledge, beauty and your popularity?

The Psalmist is grieving over the fact that the wicked is still out there not being punished. However, when I was mediated on this, I thought of me decorated the same as the wicked. My decoration is evident to God. But how can I escape my final judgment? I thought of our lord who was clothed with purple robe, and thorny throne for mockery. And then I understood which decoration is should wish people to see in me. It is decoration of Jesus Christ our Lord and his humility, love, and salvation for me. He is surely my escape, my refuge, my help and my portion forever.
