וַיַּחְפְּר֧וּ כָל־מִצְרַ֛יִם סְבִיבֹ֥ת הַיְאֹ֖ר מַ֣יִם לִשְׁתּ֑וֹת כִּ֣י לֹ֤א יָֽכְלוּ֙ לִשְׁתֹּ֔ת מִמֵּימֵ֖י הַיְאֹֽר׃
애굽 사람들은 하수 물을 마실 수 없으므로 하숫가를 두루 파서 마실 물을 구하였더라
Targum Jonathan on Exodus
And the Mizraee digged about the river for water to drink, but could not find them pure; for they were not able to drink of the water from the river.
