Genesis 43:20

And said, O sir,.... Or, "on me, my lord" a, one said in the name of the rest, perhaps Judah, on me let the blame lie, if guilty of rudeness in making our address to thee; or as the Vulgate Latin version, "we pray, sir, that thou wouldest hear us"; and so Jarchi and Aben Ezra say the phrase is expressive of beseeching, entreating, and supplicating:

we came indeed down at the first time to buy food; not to spy the land but to buy corn, and not to get it by fraud or tricking but by paying for it the price that was required.
