Stay quiet in the holy place, wait for your God to make decision
The staffs are placed before the ark of the covenant. It is like our worship, that we place ourselves before God and let Him judge our problems.
Next day, they saw only Aaron's staff sprouted, budded blossomed and produced almonds. That miracle has two meanings:
(1)God surely chose Aaron
(2)God gives life even into a dead wood.
Let us be silent and place ourself before God, let Him as He does anything for us. Before Him, anyone get life, even if you think yourself dead, useless, or hopeless.
