Ibn Ezra

My voice (קוֹלִי - koli): And the meaning is: I will not enter into battle, but rather I will lift up my voice in prayer. From His holy mountain (מֵהַר קָדְשׁוֹ - me-har kodsho): Because of the Ark that was in Zion [having been brought by David earlier, cf. II Samuel 6], it [Zion] is called the holy mountain. And this [psalm, referencing Zion as the location of the Ark] precedes the incident involving Araunah the Jebusite [i.e., David's purchase of the threshing floor which later became the Temple site, II Samuel 24].
