13

He hath also prepared for him the instruments of death; he ordaineth his arrows against the persecutors.

14

Behold, he travaileth with iniquity, and hath conceived mischief, and brought forth falsehood.

15

His mischief shall return upon his own head, and his violent dealing shall come down upon his own pate.

I will praise the Lord according to his righteousness: and will sing praise to the name of the Lord most high.

Hell Terminology (Sheol/Hades/Gehenna/Lake of Fire)

The verse describes a person falling into a literal pit they dug, using metaphorical language for self-inflicted harm or consequence, rather than referencing a specific theological place of punishment like Gehenna or the Lake of Fire.
