Rashi on Genesis 30:20/רש"י על בראשית ל׳:כ׳

1זבד טוב A GOOD DOWRY — explain it as the Targum renders it: a good portion.

2יזבלני WILL RESIDE WITH ME — It has the same meaning as (1 Kings 8:13) “a house for dwelling (זבול)”. In old French herbergerie, a dwelling house. Leah meant: From now on his real home will be with me since I have as many children as all his other wives together.
