סוֹמֵ֣ךְ יְ֭הוָה לְכָל־הַנֹּפְלִ֑ים וְ֝זוֹקֵ֗ף לְכָל־הַכְּפוּפִֽים׃
גאָט לענט אונטער אַלע געפֿאַלענע, און שטעלט אױף אַלע געבױגענע.
Rashi
they will fall into it They will ultimately fall into it. כפף is cline, or clina in Old French, bent, bent down, an expression of (below 145:14): “and straightens all who are bent down (הכפופים).”

And our Sages said (Tanchuma Teitzei 1) if you fulfill the commandment of making a parapet [for your roof], you will merit a vineyard. What is the connection between a parapet and a vineyard? It is because wine causes the drunk to fall, as derived in Yalkut: Just as the vine is harvested and remains silent, and afterward they give it to a person and it makes him fall, etc. — see the end of Parashat Vayeshev (40:146). Therefore, specifically after making the parapet which protects from falling, you will merit a vineyard, and not before then, “lest the faller fall from it.” A hint to this matter: the final letters of “ki yipol hanofeil” [lest the faller fall] add up numerically to “yayin” [wine].
And know that the section of sending away the mother bird begins with the letter ‘kaf’ and ends with ‘mem’, which together form the word “samech” [meaning support], and similarly the sections about the parapet and vineyard begin with ‘kaf’ and end with ‘mem’, referencing the verse God supports all who fall (Psalms 145:14). For regarding sending away the mother bird, the Sages discuss a case where a father tells his son to climb up to a building and bring bird chicks, and the son climbs, falls, and dies — where is the long life promised to this person? God supported him by giving him long life in the world that is entirely long [the World to Come] (Chullin 142a). And in making a parapet, God supports all who are liable to fall. And regarding “do not sow your vineyard with diverse seeds,” one is not liable until he sows wheat, barley, and grape seeds with one throw of the hand (Berachot 22a), which would cause one kindling of fire [punishment] (Kiddushin 56b). However, when one does not sow in this manner, “God supports all who fall” with the throw of the hand. The Rivah explained something similar to this, and from his explanation you can see what I have added of my own.

the law of the plague of ṣara‘at of a garment of wool Four consecutive nouns in the construct case! There is even, in Scripture, an instance of five: “men of valor for the work of the service of the house of God” [I Chronicles 9:13] — all dependent upon God, Who supports all who become dependent.
