Allow me to expand a little.

Here is a short section from Collins on The Similitudes of Enoch:

Righteousness is rather an attitude of rejecting this world and having faith in the Lord of Spirits and the Son of Man. Faith here involves both belief in the existence of the Lord of Spirits and the Son of Man, and trust and dependence on them for salvation. We should note that the Similitudes do not explicitly refer to keeping the law or distinguish between Jew and Gentile.

If we assume a dating of the similitudes of mid 1st century CE, then we’re talking about a very similar period to Paul. I am intrigued by how recognisable the concept of righteousness through belief here is to Pauline theology.

So, exploring the idea that righteousness by faith was not a purely Pauline invention… where did the idea come from? At some point in history one of the ancient religions must have shifted focus from cultic practice to become more faith based. I would be sceptical that this was just a phenomena in Jewish apocalyptic thinking.
