Chasidut zu Jeschijahu 6:10

3. So now we can say that this itself is the aspect of "Four categories have to give acknowledgement," for, corresponding to the four parts of speech that are perfected by them, specifically by thanksgiving, namely through the four who have to give thanks, through them the fourfoldness of speech is made whole, as mentioned. And that is why there are four who have to give thanks, corresponding to the four parts of speech that are made whole through them: [1 Choleh] For, one who was ill and got well and acknowledges it to H"Y, this is the aspect of teshuvah, for, "A person does not get up from his sickness unless they forgive him all his transgressions," namely through teshuvah, as written, "Veshav verafe lo/and he return and he gets healed" [Isa. 6:10]. [2 Yam] Those who go down to the sea, this is the aspect of speech of charity, as brought in Yonah, regarding the people that were with him on the ship, who swore an oath, for tzedakah is the aspect of the sea, the aspect of water, as written, "and righteousness as a mighty stream" [Amos 5:24], the aspect of "Shelach lachmekha `al penei hamayim/Cast your bread on the face of the water" [Eccl. 11:1]. [3 Yesurin] One who was locked in prison who goes out from captivity, this is the aspect of the wealthy who are close to Malkhuth [Rashi on Chullin 92a], that through them is the path whereby the captive goes out from imprisonment, the aspect of the "Shelosheth haserigim/the three branches," "hasheloshah sarei ge'im/the three high noblemen" [Chullin 92a] by whom Yosef went out from prison, as explained in Torah. [4 Midbar] Wilderness, this is the aspect of the essence of speech, the aspect of Malkhuth-mouth, because wilderness alludes to speech itself, as explained in the holy Zohar. For, wilderness is the aspect of speech, that is, the aspect of Malkhuth-mouth, which is the essence of speech.
