And Moses and Aaron did as the Lord commanded
them
After this they never showed any reluctance, or made any
objection to any message they were sent with, or any work they
were ordered to do, but went about it at once, and performed it
with all readiness and cheerfulness:
so did they;
which is not a superfluous and redundant expression, but very
emphatic, showing with what care and diligence they did every
thing, and how exactly they conformed in all things to the divine
will.
