His role as a cupbearer also required him to be upbeat at all costs. Kings and rulers did not want anyone hanging around that bring unhappiness.
One commentary said that in order to keep the king happy and to not do anything that would change his mood; this position required the cupbearer to walk with his hand over his mouth so as not to defile the king smell with his breath.
They were to keep a cheerful disposition regardless of their personal life.
And up till now, Nehemiah was able to do that. But after this long, it began to weigh on him.
This was also a potentially dangerous thing to do. Kings were always on the lookout for any type of coup’. Or rebellion. Any nervous looks on their staff could mean trouble and the king would just take action.
So the king opens the door for Nehemiah to start talking.
You never know when something in your countenance or conversation my trigger a question or a God-ordained opportunity, that is in effect an open door to step out in faith.
We often times pray for God to open a door for us to walk thru. But how often does that door open that we don’t walk thru?
Now is where the rubber meets the road for Nehemiah.
