Rashi on Genesis 37:7/רש"י על בראשית ל״ז:ז׳

1מאלמים אלמים — Understand it as the Targum renders it: were binding bundles i.e. sheaves. Similar is (Psalms 126:6) “bearing (אלומותיו) its sheaves”. Similarly in Mishnaic Hebrew we have (Bava Metzia 22b) “and he takes (האלומות) the sheaves and makes public proclamation”.

2קמה אלמתי means it raised itself erect.

3וגם נצבה means remaining erect in its place.
