תָּכִ֣ין בַּקַּ֣יִץ לַחְמָ֑הּ אָגְרָ֥ה בַ֝קָּצִ֗יר מַאֲכָלָֽהּ׃
גרײט זי אָן אום זומער איר ברױט, האָט זי אָנגעקליבן אין שניטצײַט איר שפּײַז.
Akeidat Yitzchak
In verse fifteen we read about five staggered cases of decay, corruption, which are introduced by the caption "Yeshurun grew fat and kicked." The result was a) you became fat; b) you grew coarse; c) you grew gross; d) he forsook the Lord who had made you; e) he spurned the Rock of his support. The specific acts of rebellion are listed in verse 16-18. G'ds response which was equally staggered, is listed in verses 19-25. The penalties listed 1) sword, 2) hunger; 3) wild beasts; 4) pestilence, correspond to the four basic elements the earth is made of, i.e. fire/sword; water/famine; dust/wild beasts; air, ruach /pestilence.
Duties of the Heart
"Go to the ant, lazy one! observe its ways and become wise; she prepares her bread in the summer; [for she has no chief, overseer, or ruler; she gathers her food in the harvest. O lazy one, how long will you lie there; when will you get up from your sleep?]" (Mishlei 6:6-9)
