Genesis 43:12 Halakhah

וְכֶ֥סֶף מִשְׁנֶ֖ה קְח֣וּ בְיֶדְכֶ֑ם וְאֶת־הַכֶּ֜סֶף הַמּוּשָׁ֨ב בְּפִ֤י אַמְתְּחֹֽתֵיכֶם֙ תָּשִׁ֣יבוּ בְיֶדְכֶ֔ם אוּלַ֥י מִשְׁגֶּ֖ה הֽוּא׃

and take double money in your hand; and the money that was returned in the mouth of your sacks carry back in your hand; peradventure it was an oversight;
