Psalm 55:15 calls for sudden judgment upon the psalmist's treacherous and violent enemies, using the severe imagery of descending alive to the realm of the dead. In context it is an imprecatory prayer for divine justice rather than a specific prediction about the manner in which a future betrayer would die.

Matthew 27:3-5 records Judas's remorse and suicide after betraying Jesus, while Acts 1:16-19 reflects upon his betrayal and death as events connected with Scripture. Acts does not cite Psalm 55:15 for Judas's death, so the relationship should be stated cautiously. The psalm contributes to the broader biblical pattern of judgment upon treachery, but the specific details of Judas's unrepentant end come from the New Testament narrative rather than from a direct prediction in Psalm 55.
