Quoting Commentary for Isaiah 30:1

Rabbi Meir said: even though there is no proof of the matter, there is a hint: “So that no shard is left in its breakage to scoop coals from a brazier” (Isaiah 30:1. Rabbi Yose said to him: proof [of my view] is from there [as well]: “Or to take ladle water from a puddle” (. In this section Rabbi Meir tries to prove from a verse in Isaiah that shards were used for scooping out coals. Rabbi Yose responds that if that verse is going to be used, why not look to the end of the verse which proves that shards were also used to ladle water. Therefore, a shard that is large enough to use to draw water is already large enough such that one who carries it is liable for carrying on Shabbat.

that it be included [Hebrew: sefot] 1) Rabbi Y e hudah HaLevy — may he be for us a light from above! — said that this word has the meaning of “termination” (as in “will you destroy…” [Hebrew: tispeh] [Genesis 18: 23]). The man engaged in blessing himself intends to nullify the words of the righteous — here denoted by the word moist — by means of the words of the “thirsty” (the righteous man is called moist, along the lines of “like a tree planted by the water” [Jeremiah 17: 8], whereas a wicked man is called thirsty, along the lines of “like a juniper bush in the desert” [Jeremiah 17: 6]). Likewise, he thinks that by blessing himself, he can cancel out the malediction. All this would have been a fine explanation — were it not for the fact that moist is an adjective; the verse would have to read “…moisture with thirst”. 2) The grammarian Rabbi Yona ibn Janaḥ explained the verse to mean: Since he sees that the innocent are destroyed the same as the wicked, he decides in his heart to be wicked. This cannot be right, though, on account of the phrase all will be well with me. In my opinion, the word included [Hebrew: sefot] denotes an accretion, as in “that sin be added [Hebrew: sefot]” [Isaiah 30: 1]. The meaning is: “all will be well with me, even though I follow the evil impulses of my heart, because I will survive through the merit of the righteous; they are many, whereas I am just a single sinner”. For this reason, Scripture immediately says, God will not consent to pardon him — that is, he will be instantly destroyed. The image is of something wet adding moisture to something parched. Scripture compares the righteous man to land that is watered (as in, “like a tree planted by streams of water” [Psalms 1: 3]) and the wicked man to land that is parched (as in “like a juniper bush in the desert” [Jeremiah 17: 6]). Evidence for this interpretation is provided by the beginning of the passage: “a root developing into hemlock and worm-wood” [: 17] — which only occurs in a dry area.

from all your sins As I have explained, [comment on Exodus 34:6], the noun “sin” is a general category. You will find it used to denote both unintentional acts [Deuteronomy 19:15] and intentional thoughts [Isaiah 30:1].
