There are many traditions about the staff used by Moses and Aaron.
Jacob had it when he crossed the Jordan (Gen.32:11); he passed it
on to Judah (Gen.38:18, 49:10); Moses took it to Egypt (Ex.4:17,20),
where he and Aaron performed many miracles with it. If it was the
same as Aaron's staff that blossomed (Num.Ch.17), it was kept in
the Ark, and was used by the kings of Judah - in particular, by
David when he fought Goliath (1 Sam.17:40). It disappeared when
the First Temple was destroyed.
