Nehemiah 4:9 But we prayed to our God and posted a guard day and night to meet this threat.
Thought:Even though God is on their side, they still posted a guard day and night to meet the opposition to the rebuilding of the temple i.e do something to protect themselves even though they had faith in God will fight for them. It is a bit like by faith we know God will bless us with our daily needs but we should still need to put in our best effort.
