Was Goliath's armor kept in David's tent or in Nob? - 1 Samuel 17:54; 21:1, 9

Question

Where was as Goliath's armor kept, in David's tent or in Nob? - 1 Samuel 17:54; 21:1, 9

Answer

1 Samuel 17:54 David took the Philistine's head and brought it to Jerusalem, and he put the Philistine's weapons in his own tent.
1 Samuel 21:1, 9 David went to Nob, to Ahimelech the priest. Ahimelech trembled when he met him, and asked, "Why are you alone? Why is no one with you?" ... 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."

The verses speak of two different time periods. At first it was placed in David's tent (1 Sam. 17:54), but later it was taken to Nob (1 Sam. 21:1, 9).
