'Things' in the Bible

But these speak evil of whatever things they don't know. What they understand naturally, like the creatures without reason, they are destroyed in these things.

to execute judgment on all, and to convict all the ungodly of all their works of ungodliness which they have done in an ungodly way, and of all the hard things which ungodly sinners have spoken against him."

These are murmurers and complainers, walking after their lusts (and their mouth speaks proud things), showing respect of persons to gain advantage.
