'Wrathful' in the Bible

Then Moses said to Aaron and to his sons Eleazar and Ithamar, “Do not uncover your heads nor tear your clothes, so that you will not die and that He will not become wrathful against all the congregation. But your kinsmen, the whole house of Israel, shall bewail the burning which the Lord has brought about.

then I will act with wrathful hostility against you, and I, even I, will punish you seven times for your sins.
