A powerful call is directed at the audience to reflect on the great deeds of God. This song was originally recited over the Ark of the Covenant, acting as a vivid reminder of the miraculous events that accompanied it throughout its journeys. In the daily routine of the Temple service, this specific section of the song was chanted regularly during the morning daily sacrifice, while the later portion was reserved for the afternoon daily sacrifice [רש"י].
The memories brought to mind focus specifically on the miracles that occurred around the Ark. These include the plague of mice that struck the Philistines after they captured the Ark in battle, the unnatural behavior of the nursing cows who pulled the cart carrying the Ark straight ahead without turning back to their calves, and the sudden tragedy that befell Uzzah when he reached out to hold the Ark [רש"י].
Beyond these physical miracles, the song also reflects on God's spoken decrees, which are understood in two distinct ways. One approach suggests that this refers to the Commandments and laws that God instructed the Israelites to observe [ביאור שטיינזלץ]. An alternative perspective views these decrees as a reference to the punishments and judgments that God brought upon idol-worshipping nations simply through the word of His mouth [מצודת דוד].
