Genesis 18:5

וְ אֶקְחָה פַת לֶחֶם וְ סַעֲדוּ לִבְּכֶם אַחַר תַּעֲבֹרוּ כִּי עַל כֵּן עֲבַרְתֶּם עַל עַבְדְּכֶם וַ יֹּאמְרוּ כֵּן תַּעֲשֶׂה כַּ אֲשֶׁר דִּבַּרְתָּ

And I am taking a broken-piece⁶³⁰ of bread, and supporting⁶³¹ your heart, the back you are passing-by,⁶³² for upon an upright you have crossed-over your slave.` And they say, `Thus you are making as when you have ordered.`
