'Wax' in the Bible

I am poured out like water,and all my bones are disjointed;my heart is like wax,melting within me.

As smoke is blown away,so You blow them away.As wax melts before the fire,so the wicked are destroyed before God.

The mountains melt like waxat the presence of the Lord—at the presence of the Lord of all the earth.

The mountains will melt beneath Him,and the valleys will split apart,like wax near a fire,like water cascading down a mountainside.
