On: The Chapter In The Bible That Appears Twice

[callmeed]

I believe Psalm 14 is considered a "song" while Psalm 53 is thought to be an "instructional" sermon. So they very well could be the same message/theme, just modified for singing vs. teaching.

[ars → callmeed]

An additional explanation (by Rashi) is that the first one is about the destruction of the first temple, and the second one about the second temple.

I don't know why it was left out of the translation, but 53 starts: For the conductor, on the machalath [a kind of music instrument].

And 14 starts with just: For the conductor.
