Psaumes 3:5

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].

I cry unto the Lord with my voice: – i.e. unto the Lord with my voice, for I cry to Him by reason of (my) distress.

And He answered me: – a past (tense) in place of a future, equivalent to “and He will answer me”; and there are many similar cases. Or, it may be taken according to its literal sense; for he was confident of this. Or the Holy Spirit made a revelation upon his tongue; and this is the correct view – for we have already interpreted that all the Psalms were uttered in the Holy Spirit. And in the greater part of prophecy this is found, that the speaker uses a past tense in place of a future; for it is as though the thing had already happened when it has been spoken in the Holy Spirit.

out of His holy hill. Selah: – We can interpret (this) of Mount Moriah. And although it was not yet holy, it may be that there was a tradition among them that the Sanctuary would be there. And because of this David, in his flight, ascended the Mount of Olives and from thence worshipped God; for from thence one can see that (holy) place. Or the interpretation of out of His holy hill (may be): from Mount Sion, where the Ark was. Or the interpretation of out of His holy hill (may be) out of heaven, as “Who shall dwell in Thy holy hill?” (Ps. 15:1).
