Made by melting the combs of bees. Mentioned (Ps. 22:14; 68:2; 97:5; Micah 1:4) in illustration.
Wax
Wax appears in the Psalms and the prophets as a picture of what cannot stand near heat. “As wax melteth before the fire, so let the wicked perish at the presence of God,” says Psalm 68:2. Psalm 97:5 says the hills melted like wax at the presence of the LORD, and Micah 1:4 describes mountains molten and valleys split open before him. In Psalm 22:14 the same image turns inward, as a suffering man feels his own heart is like wax, melted within him. Two uses, one picture: nothing, from hills to a human heart, is steady apart from God’s presence.
4 verses
Psalms
I am poured out like water, and all my bones are out of joint: my heart is like wax; it is melted in the midst of my bowels.
As smoke is driven away, so drive them away: as wax melteth before the fire, so let the wicked perish at the presence of God.
The hills melted like wax at the presence of the LORD, at the presence of the Lord of the whole earth.
Micah
And the mountains shall be molten under him, and the valleys shall be cleft, as wax before the fire, and as the waters that are poured down a steep place.
