Ecclésiaste 11:5

Just as you do not know, etc., nor the nature of that which is hidden in the womb of her that is with child. Things closed in and confined in the womb which is full, and even though it protrudes outward, “just as you do not know [the way of the wind].” This is a transposed verse, expounded from its end to its beginning. “Just as you do not know the way of the wind,” i.e., the knowledge of both these things is equal, neither is one revealed to you, nor is the other revealed to you, for sometimes you think that you know by the clouds that the wind will come, and it does not come here, but it passes and goes away to another land. This expression is similar to, “like the garden of Adonoy, like the land of Egypt,” [and] “as with the maidservant, so with her mistress,” [and] “as with the buyer so with the seller.” Sometimes it [Scripture] compares the former to the latter, and sometimes it compares the latter to the former. Here too, it teaches the knowledge of the wind from the knowledge of the womb, i.e., you should not await the wind by looking at the clouds. (Gloss: This matter is transposed in Rashi’s words, and it is in the opposite order. We must therefore, emend it as it is in exact editions, and then it will be understood well, and the following is the authentic version:

Just as you do not know. This is a transposed verse, explained from its end to its beginning: Just as you do not know the skeletal structure that is enclosed in the full womb, things that are closed and confined in the full womb, and even though it protrudes outward, you cannot fathom what is in her womb, so do you not know the way of the wind, i.e., the knowledge of both these things is equal, etc. From the book Sifsei Chachomim.)

Nor the nature of that which is hidden. Enclosiede in O.F., as in, “and closes וְעוֹצֵם his eyes.”

So you will never know, etc. Also the decrees of the Omnipresent in dealing with poverty and wealth are hidden from you, and you should not refrain from [doing] kindness because you are worried, “perhaps my wealth will diminish and I will become impoverished; I will [therefore] not engage in Torah [study] and neglect my work and become poor; I will not wed and have children, because I will have to spend money to support them.”
