In De 32:35; Ro 12:19; Heb 10:30; Jude 1:7, means retributive justice- a prerogative of God with which those interfere who seek to avenge themselves. So also in Ac 28:4; though many suppose that the islanders meant the goddess of justice, Dike, whom the Greeks and Romans regarded as a daughter of Jupiter, and feared as an independent, just, and unappeasable deity.
When the natives saw the creature hanging from his hand, they said to one another: "Evidently this man is a murderer, for though he has been saved from the sea, Justice has not allowed him to live."
Never avenge yourselves, dear friends, but make way for the Wrath of God; for Scripture declares--'"It is for me to avenge, I will requite," says the Lord.'
