Jesus spoke constantly in parables.

A parable is a comparison between a new idea and something the listener already understands.

Jesus's listeners' identity was tied to the Exodus, where their ancestors endured 40 years of harsh treatment, being tested in the desert by YHWH to force obedience.

Christians, however, know next to nothing about the Exodus. It isn't even a small part of their identity. They have zero connection to it, and most have never read the Torah even once. As a result, they completely miss that Jesus frequently references the Exodus in His parables.
