וַתָּבֹ֗א וַתַּגֵּד֙ לְאִ֣ישׁ הָאֱלֹהִ֔ים וַיֹּ֗אמֶר לְכִי֙ מִכְרִ֣י אֶת־הַשֶּׁ֔מֶן וְשַׁלְּמִ֖י אֶת־נשיכי [נִשְׁיֵ֑ךְ] וְאַ֣תְּ בניכי [וּבָנַ֔יִךְ] תִֽחְיִ֖י בַּנּוֹתָֽר׃ (פ)
Vino ella luego, y contólo al varón de Dios, el cual dijo: Ve, y vende el aceite, y paga á tus acreedores; y tú y tus hijos vivid de lo que quedare.
Or HaChaim
וצויתי את ברכתי, "And I shall command My blessing, etc." The blessing referred to in this verse does not pertain to the growth of the crop; that blessing has already been mentioned when the Torah spoke of the earth giving its full yield. The blessing the Torah speaks of here is in the nature of what we read in Kings I 17 and Kings II chapter 4 where the prophet made the little bit of oil of the respective petitioners stretch miraculously. This is alluded to in the words of our verse that ועשת את התבואה, i.e. that the existing crop will be made to last for three years. My comments on Genesis 33,9-11 are relevant to this verse.
