עַל־כֵּ֖ן יִתְרָ֣ה עָשָׂ֑ה וּפְקֻדָּתָ֔ם עַ֛ל נַ֥חַל הָעֲרָבִ֖ים יִשָּׂאֽוּם׃
C’est pourquoi les biens qu’ils avaient amassés, leurs objets précieux, ils les transportent au delà du torrent des saules.
Rashi
Their haughtiness, which is absorbed within them does it not leave [them]? Heb. יתרם בם, like (Isa. 15:7), “Because of haughty things (יתרה) they did.” Their haughtiness and their wisdom, which is absorbed into their body—behold it will move away and be uprooted from them, like (ibid. 33: 20), “whose pegs shall never be moved (יסע).”
Rashi
with a bowstring Heb. יתר (with measure for measure and with exactitude, like an arrow on a bowstring. Not in all editions.) Or, יתר can be interpreted as a rope for a rope, a line for a line. Another interpretation: יתר is an expression of haughtiness, as (in Isa. 15:7): “Because of the haughtiness (יתרה) with which they acted.”
Rashi
Because I loved Heb. על-כן. Because I loved Your commandments, it is fitting that You teach me a time of good will, and what I should do for You that You should accept me. There are many [instances of] על-כן that are to be interpreted as “because”; e.g., (Gen. 33:10): “because (כי על-כן) I have seen your face”; (Num. 10:33). “because (כי על-כן) you know our encampment”; (Isa. 15: 7), “Because of (כי על-כן) the many things they did.”
