EXTRA side-ring · Parashas Va’eschanan · Passuk 3:29
So we abode in the valley opposite Beis-Peor.
Classical: midrashic note on the proximity of the camp to the site of the Peor sin (cf. Bamidbar 25; Sanhedrin / midrashim on residual danger).
English: “And we abode in the valley opposite Beis-Peor” — to teach that they were still near the place of the earlier failure, and yet they did not return to that failure.
Custom / Aggadah — geographic note as moral reminder.
Even when Israel camped opposite the site of a previous national sin, they did not relapse; proximity to failure need not produce repetition.
