Remember His wonders the plague of the mice, and they took milch cows and shut up their young in the house, and the cows went straight (I Sam. 6:10-12), and they did not turn back, and the breach of Uzza. The entire song was composed concerning the Ark, and they would say it for the daily sacrifice in the morning, and “Sing to the Lord,” for the daily sacrifice in the afternoon (Seder Olam ch. 14). And to whom do I say that they should remember the wonders of the One Who is perfect in knowledge?
Rashi
And say, “Save us At the end of the Psalm (106:42), which speaks about captivity: “And their foes oppressed them, and they were humbled under their hand,” it is written thereafter, (ibid. verse 46): “And He caused them to be pitied by their captors.” Now, it is appropriate to say, “Save us, O Lord our God, and gather us from the nations,” as You have done to them. In Psalms, it does not say, “And say, save us” but only, “Save us,” because that is the appropriate wording. For the following reason, David recited these two psalms when he brought the Ark: It is explained in Genesis Rabbah (54:4): “since the cows, when they sang, recited these two psalms.” Rabbi Samuel the son of Nahmani said: (I Sam. 6:12): ‘And the cows sang.’ What song did they sing? ‘Give thanks to the Lord, call out in His name.’ Rabbi Eleazar says: ‘Sing to the Lord, all the earth, etc.’” Therefore, David instituted them to recite them before the Ark, one psalm in the morning and one psalm in the evening. Quoted from Rabbi Eleazar the son of Meshullam of blessed memory.

ויחמנה, “they grew heated;” the construction of this word is a combination of two conjugations. It is similar in this respect to Samuel I 6,12: וישרנה הפרות, “the cows went straight, and to ארבע מלכיות מגוי יעמודנה, “four kingdoms will arise out of a nation,” and in Daniel 8,2, and in ותקרבו העצמות עצם אל עצם, “the bones came together,” in Ezekiel 37,7.
Rashi
Your might Because of the following it is called “Your might”: because it performed wonders and mighty deeds among the Philistines. And so it is written above (I Chron 16:8-36): “Give thanks to the Lord,” “Search for the Lord and His might.” Our Sages stated further in Tractate Abodah Zarah 24b (I Sam. 6:12): “And the cows sang.” What song did they recite? They said, (Ps. 98:1) “His right hand and His holy arm have gained Him the victory.”
