וְכֶ֥סֶף מִשְׁנֶ֖ה קְח֣וּ בְיֶדְכֶ֑ם וְאֶת־הַכֶּ֜סֶף הַמּוּשָׁ֨ב בְּפִ֤י אַמְתְּחֹֽתֵיכֶם֙ תָּשִׁ֣יבוּ בְיֶדְכֶ֔ם אוּלַ֥י מִשְׁגֶּ֖ה הֽוּא׃
너희 손에 돈을 배나 가지고 너희 자루 아구에 도로 넣여 온 그 돈을 다시 가지고 가라 혹 차착이 있었을까 두렵도다
Radak on Genesis
וכסף משנה, and a second amount of money. The word משנה occurs in the same sense as here in Jeremiah 17,18 ומשנה שברון, “and shatter them with double destruction.” The vowel segol instead of tzeyreh in שני, indicates that the word is not in a construct mode.
