Psalm 133/Notes/Verbal.v. 2.149100

We prefer to read the three participles יֹרֵד as progressive, yet they could also be interpreted as habitual (that is, referring to numerous distinct instances of the anointing of Aaronic priests and numerous distinct instances of the dew of Hermon flowing onto the mountains of Zion), since the participle begins to take over the habitual function of yiqtol in Late Biblical Hebrew, a period to which the Psalms of Ascent plausibly belong.
