“And may God give you from the dew of the heavens.” It is written: “My root will be open to water, and dew will lie on my branch” (Job 29:19) – Job said: ‘Because my doors were wide open, everyone would reap dry crops, and I would reap full, lush kernels.’ What is the source? “My root will be open to water.”1The verse is being interpreted as saying that the door was open and everything was available to a guest, just as water is freely available. The word root is interpreted as referring to the door since the house "begins" from the door and the tree begins from it's roots (Radal). Jacob said: ‘Because I was engaged in Torah that is likened to water, I was privileged to be blessed with dew,’ as it is stated: “And may God give you from the dew of the heavens.”
