Even though Abraham said to the visitors:
(ה) וְאֶקְחָ֨ה פַת־לֶ֜חֶם וְסַעֲד֤וּ לִבְּכֶם֙ אַחַ֣ר תַּעֲבֹ֔רוּ כִּֽי־עַל־כֵּ֥ן עֲבַרְתֶּ֖ם עַֽל־עַבְדְּכֶ֑ם וַיֹּ֣אמְר֔וּ כֵּ֥ן תַּעֲשֶׂ֖ה כַּאֲשֶׁ֥ר דִּבַּֽרְתָּ׃
(5) And I will fetch a morsel of bread, and stay ye your heart; after that ye shall pass on; forasmuch as ye are come to your servant.’ And they said: ‘So do, as thou hast said.’
In reality he did the following:
(ז) וְאֶל־הַבָּקָ֖ר רָ֣ץ אַבְרָהָ֑ם וַיִּקַּ֨ח בֶּן־בָּקָ֜ר רַ֤ךְ וָטוֹב֙ וַיִּתֵּ֣ן אֶל־הַנַּ֔עַר וַיְמַהֵ֖ר לַעֲשׂ֥וֹת אֹתֽוֹ׃
(7) And Abraham ran unto the herd, and fetched a calf tender and good, and gave it unto the servant; and he hastened to dress it.
On the other hand, the wicked say much but do not perform even a little. Thus we find Ephron saying to Abraham:
(11) ’Nay, my lord, hear me: the field give I thee, and the cave that is therein, I give it thee; in the presence of the sons of my people give I it thee; bury thy dead.’
But in the event that Abraham weighed to Ephron:
(16) And Abraham hearkened unto Ephron; and Abraham weighed to Ephron the silver . . . four hundred shekels of silver, current money with the merchant.
Ephron refused to accept anytying but 25 times the worth of the field.
(15) Shammai says: Make your Torah fixed, say little and do much, and receive every person with a pleasant countenance.
