Comentario sobre Exodo 39:43

ויברך אתם משה AND MOSES BLESSED THEM — He said to them “May it be the will of God that His Shechinah rest upon the work of your hands; ‘and let the beauty of the Lord our God be upon us and establish Thou the work of our hands upon us’” (Psalms 90:17.) (Sifra, Shemini, Mechilta d'Miluim 2 15) This (from ויהי נועם onward) is part of one of the eleven Psalms (90—100) that are in the section beginning with, תפלה למשה; (Numbers Rabbah 12:9).

והנה עשו…כן עשו, and behold they had done it…so they had done. The additional word והנה in this verse alludes to the speed with which the Tabernacle was built, something that was very pleasing to Moses when he looked at the components the people presented him with.
