Rabbi Yosi and Rabbi Yitzchak are walking together. Rabbi Yosi says that God chose Betzalel to build the Temple because of his name, which means 'in the shadow of El,' 'El' being the name of Chesed. He adds that God made names on earth because they have significance. To further this argument he says that Judah started building the left side and the Tabernacle was constructed of left and right. In the same way the Torah, Tiferet, started on the left side, Gvurah, and joined the right, Chesed. Reuben started building on the right and turned to the left to bring in the tribes Shimon and Gad. We hear that God gave Betzalel wisdom because he was already wise-hearted.
Rabbi Shimon turns to: "Like the apple tree among the trees of the wood, so is my beloved among the sons... I sat down under His shadow with great delight, and His fruit was sweet to my taste." He says that 'under His shadow' refers to Betzalel, and 'His fruit' refers to the souls of the righteous since they are the fruit of God's deeds.
Finally the verse: "All the gold that was applied" is explained as meaning that the gold that was supplied for the Tabernacle already existed above. In each work that was holy there was gold.
