Quem numerará as nuvens pela sabedoria? Ou os odres do céu, quem os esvaziará,

The words: שכבת הטל, (especially with the prefix ה indicating that the dew was a well known phenomenon,) refer to the daily descent previously of that layer of dew; we have a similar construction in Job 38,37: ונבלי שמים מי ישכיב, “who can tilt the “bottles” of the sky?” (a hint at the phenomenon of dew) The root שכב, “to come to rest in a prone condition,” is used in both these verses.

HaKtav VeHaKabalah
You shall count for yourselves. The word chosen for designating counting (וספרתם) alludes to the soul’s benefit — becoming sanctified and purified from all materialistic desires and lowly thoughts during this seven week period. For even the word תספור (count) does not connote merely to know how many days and weeks, rather, it implies analysis and watchfulness, as it says, “But now, You count my steps” (Iyov 14:16). This mainly implies analysis and watchfulness of one’s steps and behavior. Similarly, here too, the meaning of “you shall count for yourselves” is that you should inspect your lives, think deeply about yourself — what is the true good you should choose and the true evil from which you must flee. Do not do anything without weighing it first in the scales of judgment to see if it is good or bad. This can be compared to someone who received a sum of money from his friend. He will be careful about the amount of the coin count and also the quality of each counted coin, lest he have an invalid, defective coin … Possibly, we can also say that in using the word וספרתם the Torah includes the idea of purity and refinement, as the language of the verses (Yechezkel 1:26): “Sapphire (ספיר) stone,” and (Shemos 24:10), “Sapphire brick.”.
Ibn Ezra
semen as in, “a layer of dew” [Exodus 16:13] from “who can refill” [Job 38:37]. Those commentators err who explain all of his flesh as a reference to the male genitalia [see comment on :2]: their error lies in ignoring the word all .
