Moses speaks to the Israelites as if they were one man, so the words "you" and "your" here are singular. (See: [[rc://en/ta/man/translate/figs-you]])
# you have passed ... set up ... I am commanding you
Moses is addressing the Israelites as a group, so the instances of "you" and the command "set up" are plural. (See: [[rc://en/ta/man/translate/figs-you]])
