Job 18:13

¹¹ Terrors shall make him afraid on every side, and shall drive him to his feet.

¹² His strength shall be hungerbitten, and destruction shall be ready at his side.

It shall devour the strength of his skin: even the firstborn of death shall devour his strength.

¹⁴ His confidence shall be rooted out of his tabernacle, and it shall bring him to the king of terrors.

¹⁵ It shall dwell in his tabernacle, because it is none of his: brimstone shall be scattered upon his habitation.

Do read the surrounding verses too, because the context often says more than a single verse.
