פְּלָא֥וֹת עֵדְוֺתֶ֑יךָ עַל־כֵּ֝֗ן נְצָרָ֥תַם נַפְשִֽׁי׃
Peringatan-peringatan-Mu ajaib; karena itu jiwaku memeliharanya.
Rashi
Your testimonies are hidden They are covered, and your testimonies are hidden from the sons of men. There are easy commandments for which He gave a large reward, such as sending away the nest.
Malbim
(Testimonies) Wonders - In the section of testimonies in the Torah there are wonders. These are things that are extraordinary and hidden matters, that beyond the revealed narratives, that are all true according to their simple meaning, there is secrets and mysteries. This is like the subject of the Garden of Eden, the [4] Rivers, the Serpent, the Nephillim and the kings that reigned in the land of Edom, and other similar subjects.
Rashi
therefore, my soul kept them All of them, because it is not known which is better.
