Comentario citado sobre Isaías 58:5

When a man makes an explicit vow, etc. This section is juxtaposed with the curses to indicate that Israelites make vows in times of trouble, like Jacob who vowed in a time of distress to give a tenth of everything. However, they are not completely like Jacob, for Jacob did not deviate from the good path even after the trouble passed. But for later generations, this becomes their foolish way: they make vows during times of distress, but when the storm of affliction passes, they regret and return to their misdeeds. This is like the parable of the reed with which Ahijah the Shilonite cursed Israel (1 Kings 14:15), for this reed only bends when the wind blows upon it, but when the wind subsides, it returns to its upright position as before. Similarly, Israel only humbles itself when distress prevails, but when Israel saw that there was relief, he hardened his heart, for when the compelling force is removed, they return to their misdeeds.
Supporting our interpretation is what the Baal HaTurim (27:1) explained: That the total number of shekels is 143 [in this section], corresponding to the 143 curses in Leviticus and Deuteronomy (see Midrash Tadsheh, Otzar HaMidrashim p. 480). And is it merely because their numbers are equal that they are juxtaposed? Rather, it is to tell you that the 143 curses in the rebuke cause the vows of 143 shekels, for Israel only vows to give of their wealth to God when troubles compel them to do so.
As will be explained, God willing, later in Parashat Vayelech (31:17) on the verse And many evils and troubles shall befall them (Deuteronomy 31:17), which our Sages interpreted (Chagigah 5a) as referring to one who lends to a poor person in his time of need. This interpretation is difficult to accept — that all troubles would not compel them to confess except this particular trouble. Therefore, I wish to explain that this speaks of one who lends to a poor person specifically when trouble comes, meaning in the lender’s own time of distress, for troubles press him to make vows for charity. The mistake of one who makes vows in this manner will be explained, with God’s help, later in Parashat Vayelech. Hence, the section about when a man makes an explicit vow is juxtaposed with the section of rebuke, and the verse speaks of what commonly occurs. But whatever a person does without compulsion, willingly, this is called a day of favor to the Lord (Isaiah 58:5) and obtains favor from the Lord (Proverbs 8:35).
The book of Leviticus is completed — with the help of the great, mighty, and awesome God.
