Ibn Ezra on Genesis 31:30/אבן עזרא על בראשית ל״א:ל׳

1LONGEST. Nikhsof (longest) is an infinitive in the nifal. It is similar to nilchom (fight) in or did he ever fight (nilchom) against them (Jud. 11:25).

2The word nikhsafta means thou longest. Yikhsof (eager) in He is like a lion that is eager (yikhsof) to tear in pieces (Ps. 17:12) is similar.
