דברי הימים ב, פרק כ״ח, פסוק ד׳

Acts of worship were carried out across several prominent and visible locations. Rituals took place at the high places, atop hills, and beneath the shade of any thriving, leafy tree. During these gatherings, the act of sacrifice specifically involved the slaughtering of animals. This practice was not done in isolation; rather, the animal offerings were made right alongside the burning of incense at these very same sites [ביאור שטיינזלץ].
