Rabbi Elazar ben Arach

The paradigm of חידוש

The original מעיין המתגבר

Was drawn after wine and bathing

Disconnected from his Torah

And forgot it

Instead of reading

החדש הזה לכם

He read

החרש היה לבם

Dalet and chof resemble resh and beis

Confusing them seems reasonable

But a yud instead of a zayin

Is a chiddush
