Rashi on TanakhPsalms 135

He made lightning for the rain They are the flashes in the sky, that flash and lighten before the rain; esloyde, esluyde, esludes, esloisdes, aleydonz in Old French.

He finds Heb. מוצא, an expression of finding. i.e., He prepared a treasury for the wind, and there they are accessible to Him to send them on His mission.

in the midst Heb. בתוככי, like בתוךְ in the midst.

O Lord, Your name is eternal Like Your greatness and Your authority then, so is it also now, and You have the power to judge and to avenge us.

For the Lord will judge His people He will judge their judgment from their enemies.

and relent He will have another thought.

neither is there any breath in their mouth There is not even any breath in their mouth like an animal. Now, since they have no breath [in the mouth], he need not explain [that they do not have] the breath of the nose. This אף is vowelized with a “pattah,” whereas (115:6): “they have a nose (אף) but they do not smell,” is vowelized with a “kamatz.” (This is not found in all editions.)

those who fear the Lord These are the proselytes (I found this).
