Nothing in the house but one small jug of oil.
וַיֹּאמֶר אֵלֶיהָ אֱלִישָׁע מָה אֶעֱשֶׂה לָּךְ הַגִּידִי לִי מַה יֶּשׁ לָךְ בַּבָּיִת וַתֹּאמֶר אֵין לְשִׁפְחָתְךָ כֹל בַּבַּיִת כִּי אִם אָסוּךְ שָׁמֶן׃

וַתֵּלֶךְ מֵאִתּוֹ וַתִּסְגֹּר הַדֶּלֶת בַּעֲדָהּ וּבְעַד בָּנֶיהָ הֵם מַגִּישִׁים אֵלֶיהָ וְהִיא מוֹצָקֶת׃
