Sforno on Genesis 24:10/ספורנו על בראשית כ״ד:י׳

1ויקח העבד עשרה גמלים מדמלי אדוניו וילך. He took permission from his master to set out on the way after he made prepared the camels for the journey.

2וכל טוב אדוניו בידו, he took with him many silver and golden trinkets. He did not need to ask for permission to do this seeing that all of these items were under his authority on an all year round basis in his capacity of being Avraham’s general manager.

3ויקם וילך, on his way.
