Providing what is lacking

Avraham: (2) Looking up, he saw three men standing near him. As soon as he saw them, he ran from the entrance of the tent to greet them (...)

(5) And let me fetch a morsel of bread that you may refresh yourselves (...)”

ואקחה פת לחם … ואל הבקר רץ אברהם . Abraham said little but did a lot.

Yitzhak/ Yaakov: (27) and he went up and kissed him. And he smelled his clothes and he blessed him, saying, “Ah, the smell of my son is like the smell of the fields that the LORD has blessed.

’וירח וגו AND HE SMELLED etc.— Surely there is no more offensive smell than that of washed goat-skins! But Scripture implicitly tells us that the perfume of the Garden of Eden entered the room with him (Genesis Rabbah 65:22).

And Rabbi Elazar said: The reward for charity is paid from Heaven only in accordance with the kindness and generosity included therein and in accordance with the effort and the consideration that went into the giving. It is not merely in accordance with the sum of money, as it is stated: “Sow to yourselves according to charity, and reap according to kindness.”

כריח שדה אשר ברכו AS THE ODOUR OF A FIELD WHICH THE ETERNAL HATH BLESSED — to which God has given a pleasant perfume: it refers to a field of apple-trees. So have our Rabbis, of blessed memory, explained it (Taanit 29b).

On a related topic, the Gemara cites that Rav Yehuda said: One who goes out during Nisan and sees trees that are blossoming recites: Blessed…who has withheld nothing from His world, and has created in it beautiful creatures and trees for human beings to enjoy. Rav Zutra bar Toviya said that Rav said: From where is it derived that one recites a blessing over scent? As it is stated: “Let every soul praise the Lord” (Psalms 150:6). He explains the verse: What is it from which the soul derives benefit and the body does not derive benefit from it? You must say: That is scent. Even over items from which only the soul derives benefit, one must recite a blessing and praise God.
