Interesting point you made there. I can imagine two types of Jews on the Passover night in Egypt.
Some put their trust in the lamb blood, and just relax and enjoy the night, confident that it is sufficient.
Other Jews are more paranoid and try to help the blood with their works, praying, fasting, singing non stop to God.
In the end both houses first born are still saved because, as the main dominant view of this particular thread goes, the blood at their doorpost was sufficient.
That is how I view this never ending argument about faith alone or faith and works for salvation. 🤗
