Sforno on Genesis 31:32/ספורנו על בראשית ל״א:ל״ב

1לא יחיה. He thought that one of the servants must have stolen the teraphim in order to worship them as he had been in the habit of doing before becoming part of Yaakov’s household.

2הכר לך מה עמדי, if you can find amongst my possessions any that you recognise as belonging to you, take them!

3ולא ידע יעקב, if he had known that Rachel had taken the teraphim he would not have had the audacity to deny this. Also, he most certainly would not have cursed her by saying “he shall not live!” [actually he had not cursed the thief but the one with whom the stolen goods would be found, and in the event Lavan never did find the teraphim. Ed.]
