'Wax' in the Bible

I am poured out like water,And all my bones are out of joint;My heart is like wax;It is melted within me.

As smoke is driven away, so drive them away;As wax melts before the fire,So let the wicked perish before God.

The mountains melted like wax at the presence of the Lord,At the presence of the Lord of the whole earth.

The mountains will melt under HimAnd the valleys will be split,Like wax before the fire,Like water poured down a steep place.
