וַיָּ֣מָד אֶ֔לֶף נַ֕חַל אֲשֶׁ֥ר לֹֽא־אוּכַ֖ל לַעֲבֹ֑ר כִּֽי־גָא֤וּ הַמַּ֙יִם֙ מֵ֣י שָׂ֔חוּ נַ֖חַל אֲשֶׁ֥ר לֹֽא־יֵעָבֵֽר׃
Lalu ia mengukur seribu hasta lagi; airnya sudah menjadi sungai yang tidak dapat kuseberangi, sebab air itu telah naik tinggi, menjadi air yang harus diseberangi dengan berenang, sungai yang tidak dapat diseberangi dengan berjalan kaki.
Rashi
for the water was so high [Heb. גָאוּ,lit. became haughty,] like גָדְלוּ, became large.
Rashi
water for swimming [Heb. שָׂחוּ,] noer in O.F., to swim, water that one must swim in and not cross by foot lest it overpower him. שָׂחוּ means swimming, like (Isa. 25:11): “as the swimmer spreads out [his hands] to swim הַשׂחֶה לִשְׂחוֹת.”
