Job 18

It shall devour the parts of his skin; the first-born of death consumes his parts.

El primogénito de la muerte comerá los ramos de su piel, y devorará sus miembros.

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

The members of his body will be devoured. The firstborn of death will devour his members.
