Behalotekha
“BeHalotekha” means “when you elevate” as in “when you lift up the lamps.” Aaron is commanded to light the lamps of the menorah and the tribe of Levi is commanded to serve the sanctuary. This is also when the institution of the 2nd Pesach is established and when the Israelites grumble over only having manna to eat as well as showing rebellion against Moshe from his own siblings!
