Or HaChaim on Genesis 47:14/אור החיים על בראשית מ״ז:י״ד

1 וילקט יוסף את כל הכסף, Joseph collected all the silver (money), etc. The reason the Torah uses the expression לקט, gleaned, for the manner in which Joseph collected the money, is to tell us that after Joseph had collected there was absolutely no money left anywhere.
