In Torah reading נשא Nasso (Numbers 4:21–7:89), we discussed the dedication of the altar and the tribal offerings. You notice that Levites did not bring an offering. The Levites receive gifts because they have no inheritance.
This week’s reading, בְּהַעֲלֹתְךָ Beha’alotcha (“when you raise up” [the lamps]) starts with Aaron lighting the menorah. This symbolizes God’s eyes opening. Before the menorah and altar were dedicated, God’s eyes were symbolically closed. Now they are open and the people have God’s full attention. God’s Tabernacle is now open for business.
