The sword of Goliath the Philistine, whom you killed in the Valley of Elah, If you want it, take it

1 Samuel 21:1-15

So the priest gave him the consecrated bread, since there was no bread there except the bread of the Presence that had been removed from before the Lord and replaced by hot bread on the day it was taken away.

The priest replied, “The sword of Goliath the Philistine, whom you killed in the Valley of Elah, is here; it is wrapped in a cloth behind the ephod. If you want it, take it; there is no sword here but that one.” David said, “There is none like it; give it to me.”

Now one of Saul’s servants was there that day, detained before the Lord; he was Doeg the Edomite, Saul’s chief shepherd.

David took these words to heart and was very much afraid of Achish king of Gath. So he pretended to be insane in their presence; and while he was in their hands he acted like a madman, making marks on the doors of the gate and letting saliva run down his beard.

Achish said to his servants, “Look at the man! He is insane! Why bring him to me? Am I so short of madmen that you have to bring this fellow here to carry on like this in front of me? Must this man come into my house?”

Why?

In this situation, David needed food and weapons, so he went to ask the priest. and he got some bread which were removed from before the Lord.

In case of the dangers, David pretended he was insane.  These difficulties are training to David to bear more heavy jobs in the future.

Here the Doeg told the priest Ahimelech helped David, then later induced Ahimelech to be killed. For evil men exist around us. 

How?

No matter what I meet today, trust in the Lord and seek the way of the Lord, the blessing of the Lord will be with me.
