Psalm 133 - and its grammar

This is an odd presentation of Psalm 133. It happened sort of by accident. Green is for grammar.

A song of the steps of David See how fine and how pleasing it is that brothers live as one

שִׁיר הַמַּעֲלוֹת לְדָוִד הִנֵּה מַה טּוֹב וּמַה נָּעִים שֶׁבֶת אַחִים גַּם יָחַד

like the finest oil on the head dribbling on the beard the beard of Aaron dribbling to the mouth of his clothes

כַּשֶּׁמֶן הַטּוֹב עַל הָרֹאשׁ יֹרֵד עַל הַזָּקָן זְקַן אַהֲרֹן שֶׁיֹּרֵד עַל פִּי מִדּוֹתָיו

like the dew of Hermon dribbling on the mountains of Zion for there יְהוָה constituted the blessing life for ever

כְּטַל חֶרְמוֹן שֶׁיֹּרֵד עַל הַרְרֵי צִיּוֹן כִּי שָׁם צִוָּה יְהוָה אֶת הַבְּרָכָה חַיִּים עַד הָעוֹלָם

שִׁיר	A song of	construct
הַמַּעֲלוֹת	the steps	feminine plural
לְדָוִד	of David	proper name, David with preposition
הִנֵּה מַה טּוֹב	See how good	adverb - no agreement in gender or number
וּמַה נָּעִים	and how pleasant	adverb - again no agreement in gender or number
שֶׁבֶת	to live	infinitive in construct, weak root ישב
אַחִים גַּם יָחַד	brothers as one	masculine plural
כַּשֶּׁמֶן	as oil	- is this construct?
הַטּוֹב	the good
עַל הָרֹאשׁ	on the head	definite head - almost like English generic definite!
יֹרֵד עַל הַזָּקָן	running down on the beard	yored - the sound of brooks running - or singing! like shir which this psalm is, definite beard
זְקַן אַהֲרֹן	the beard of Aaron	specific priestly beard
שֶׁיֹּרֵד	that is running	the grammatical use of shin
עַל פִּי	to the mouth of	construct
מִדּוֹתָיו	his clothes	plural with possessive pronoun third person masculine singular
כְּטַל חֶרְמוֹן	as dew of Hermon	construct
שֶׁיֹּרֵד	that is running	repetition
עַל הַרְרֵי	to the mountains of	construct plural
צִיּוֹן	Zion
כִּי שָׁם	for there
צִוָּה	commanded	third person piel (this verb is always piel - intensive) singular. You can't see the piel from the consonants alone. So was the piel made up later than the written texts?
יְהוָה	the LORD
אֶת הַבְּרָכָה	+ the blessing	a definite blessing
חַיִּים	life	life - plural!
עַד הָעוֹלָם	to the age	another definite age - life to eternity

The grammar of Psalm 117

הַלְלוּ אֶת יְהוָה כָּל גּוֹיִם	Praise יהוה all nations
שַׁבְּחוּהוּ כָּל הָאֻמִּים	congratulate him all the peoples
כִּי גָבַר עָלֵינוּ חַסְדּוֹ	for his mercy has prevailed against us
וֶאֱמֶת יְהוָה לְעוֹלָם	and the truth of יהוה is forever
הַלְלוּ יָהּ	Praise Yah

I had a dream in the early morning and I should have immediately written it down because I forgot its clarity though not its intent. The intent is to do for the shortest psalm what I am in the process of doing for Ruth - grammar, letter by letter, word by word, phrase by phrase, meaning, textual allusions, structural form, and whatever else I can find out as I move from my native tongue to the Hebrew thought that the NT presents in translation on behalf of the Gentiles.

Structurally, the psalm opens and closes with a varied pair of brackets. The opening bracket also plays a second structural role in the first of two bi-cola. Congratulate? I chose this term to stop a mindless quick read of praise or laud. It is better if it is more like 'well done, my love.' The second 'parallel' is also surprising. The reason given for congratulations is stronger than God's desire for mercy. It has prevailed - past, completed, as in the flood waters prevailing over the earth. There seems a finality in the promise of mercy that cannot be undone. This truth is faithful in all respects and in all ages. It's a bi-colon, but not a parallel of similarity, or even of tense. Instead our reason for believing can encompass what is both complete and continuing for ever.

Psalm 117:1 is picked up by Paul (Romans 15:11) as justifying his 'Gospel to the Gentiles'. I see in the Comparative Psalter (Kohlenberger) that the LXX translators chose truth rather than faithfulness for the translation of verse 2. Verse 2 alludes to Exodus 34:6. So the psalm recognizes a universal aspect of God's mercy and lovingkindness as revealed to Moses. As Luther commented somewhere, the entire Gospel is contained in the Psalter. This Psalm implies that the mercy is universally available. Paul recognizes that universal aspect of the revelation in the Scriptures as fully expressed and realized in Jesus, son of God (Romans 1:4).

This psalm has only 17 words - so we can see them all at once. There also seems to be a remarkable foreshadowing of Psalm 118 that I just noticed - only three words are shared between these two psalms (excluding the name and some shorter words) all nations, his mercy, for ever. A curious accident of my now aging algorithm for comparing psalms.

Now here are its letters in two (three) piles - Of 62 letters, only 9 are from the non-grammatical group of 11. Of the remaining 52 letters, 17 are written in grammatical roles (omitting the prepositions from the count) leaving 36, if I haven't miscounted, of the grammatical letters acting as consonants. (Green is for grammatical, Blue for the group of letters that does not play a role in forming prefixes and suffixes, and Orange for the letters of the grammatical group of 11 that are behaving like consonants in this word.)

כָּל גּוֹיִם	all nations	all as adjective plural
שַׁבְּחוּהוּ כָּל הָאֻמִּים	congratulate him all the peoples	3rd person singular suffix הוּ following second person plural imperative, root שבח (and I cannot stay with my prodding first translation - be free in him). הָאֻמִּים is plural with definite article הָ and the root word is what? It's rare (Numbers 25:15, and Genesis 25:16) - it is not the usual root for people which would be with an ayin עַם. And though it looks a lot like the word in Psalm 2, וּלְאֻמִּים apparently it is distinguished by all my sources, English, Latin, and Hebrew as different. It is said to be derived from mother - so perhaps all who are born of woman.
