The rod — That which was laid up before the Lord in the tabernacle; whether it was Aaron's rod, which was laid up there, Numbers 17:10, or Moses's rod by which he wrought so many miracles. For it is likely, that wonder — working rod, was laid up in some part of the tabernacle, though not in or near the ark, where Aaron's blossoming rod was put.
