בראשית לח:כג פירוש: רש״י, רשב״ם, ספורנו ורד״ק

תקח לה Let that remain hers which she has in her possession (i.e. LET HER KEEP IT).

תקח לה, not literally “let her take it,” but “let her keep it.” Yehudah said that he would not make an additional effort to find her and to redeem his pledges.

הנה שלחתי, so that I have not betrayed my promise.
