Today I read 2 Kings 13:
Elisha tells a king to strike the ground with arrows, and the king strikes the ground three times, but should have struck it 5-6 times. The number of times he struck the ground was an indication of how many times he would defeat his enemies. My takeaway, is that if God tells you to do something, whether directly or through His prophet, go the extra mile, He May have it in mind to bless you in proportion to your obedience.
