Why did David refuse to wear King Saul's armor?

Rabbi Landau explains that Dovid HaMelech turned down the king's armor because it wasn't his. Before Dovid went out against Golyas, Shaul put his own armor on him: the king's armor, the winning strategy.

Dovid answered, “Lo uchal laleches b'eileh ki lo nisisi,” I can't walk in these, I never tried them. He took it all off and went down with a sling. Those were his cards, Rabbi Landau says, and he won.

The lesson reaches every strategy we borrow. Shaul's armor fit Shaul. Learn from people, he teaches, but don't confuse learning with becoming them. A strategy is built for someone's strengths, timing, and circumstances, and “your hand requires your strategy.”

Surface claim

Even a king's proven armor can be the wrong equipment for you.

Deepest human truth

Dovid won with what he had actually practiced with, not with what worked for someone else.
