'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 [by anguish] within me.

As smoke is driven away, so drive them away;As wax melts before the fire,So let the wicked and guilty perish before [the presence of] God.

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