Commentaire sur Josué 2:4

And she hid them.⁸The word וַתִּצְפְנוֹ is singular but the verse is said regarding the two men and should be plural. There are scriptural verses that speak of the plural as if it were singular. Since she was in a hurry to hide them and she hid them in a narrow place⁹She hid them in a place that normally would have sufficed for one person. it was as though they were one person. The Midrash of Rabbi Tanchuma states ‘That these two men were Pinchos and Caleiv, and Pinchos stood before them¹⁰Before the pursuers. but they did not see him because he was [invisible] like an angel.’¹¹Therefore there was no need to hide him and thus she actually hid only one man. Another interpretation: She hid each of them separately.¹²Therefore it is correct to say: she hid him. We find a similar verse: ‘Oil and incense gladden the heart’¹³Mishlei, 27:9. and it does not say יְשַׂמְחוּ לֵב, in the plural.
