וַיַּשְׁכִּ֣ימוּ בַבֹּ֔קֶר וְהַשֶּׁ֖מֶשׁ זָרְחָ֣ה עַל־הַמָּ֑יִם וַיִּרְא֨וּ מוֹאָ֥ב מִנֶּ֛גֶד אֶת־הַמַּ֖יִם אֲדֻמִּ֥ים כַּדָּֽם׃
아침에 모압 사람이 일찍이 일어나서 해가 물에 비취므로 맞은편 물이 붉어 피와 같음을 보고

Rashi
From a distance. At a distance, but because they had never seen water in that valley, they, therefore, thought that it was blood.
