וְהָיָ֥ה לִפְנֽוֹת־עֶ֖רֶב יִרְחַ֣ץ בַּמָּ֑יִם וּכְבֹ֣א הַשֶּׁ֔מֶשׁ יָבֹ֖א אֶל־תּ֥וֹךְ הַֽמַּחֲנֶה׃
But it shall be, when evening cometh on, he shall bathe himself in water; and when the sun is down, he may come within the camp.
Targum Jonathan on Deuteronomy
But at evening time let him wash with water, and on the going down of the sun he may come within the camp.
