Rashi on Genesis 30:37/רש"י על בראשית ל׳:ל״ז

1מקל לבנה STICKS OF לבנה — a tree that is called לבנה — just as you say (Hosea 4:13) “Under oaks and poplars (ולבנה)” I think it is what is called in old French tremble; English trembling-poplar, which is white.

2לח FRESH — He took it when it was moist.

3לוז ALMOND — He also took rods of לוז, a tree upon which small nuts growold French coudre; English hazel.

4וערמון is old French chastenier, English chestnut.

5פצלות STREAKS — many peelings so that he gave it the appearence of being striped.

6מחשוף הלבן MAKING BARE THE WHITE — there was thus an uncovering of the white part of the rod: when he peeled it the white in it became uncovered and visible in the places where it was peeled.
