Ibn Ezra on Isaiah
שריקות Red.13A. V., Fire. Some compare it with משרק comb, but more correctly it is derived from שורק vine branch (5:2), and it signifies, having the colour of the vine branch, red; comp. שרקים red (Zac. 1:8).
Rashi on Isaiah
to be combed Flax that they comb and from which they weave fish nets, which are made with many holes.
