“but how terrible it will be for that man.” This warning is in Matthew 26:24, Mark 14:21, and Luke 22:22. The Greek word translated “how terrible it will be for” is ouai (#3759 οὐαί; pronounced ooh-'eye). For an explanation of the meaning of ouai, see commentary on Matthew 11:21. In this context, ouai is an expression of warning of the grief, disaster, and divine retribution that is coming to the one who betrays God’s Messiah.
