What is the origin of the custom to recite in pesukai dezimra יעלוץ השדה וכל אשר בו instead of יעלוז שדי וכל אשר בו which we are familiar with from Kabbalas Shabbos (psalm 96)?
1 Answer
It's the verse Ⅰ Chronicles 16:32. The entire passage surrounding that verse in p'suke d'zimra is from Chronicles there.
