We often learn in Tanach about the great interventions of Hashem to alter the natural course of events. Sometimes these interventions involve great an open miracles like the ten plagues in Egypt, the splitting of the sea and the stopping of the sun in its path through Yehoshua.

Other times Hashem intervenes in a more subtle fashion, but just as miraculous.

The Medresh Tehillim reveals to us that three times Hashem intervened with the natural course of events and allowed that which is soft to defeat that which is hard.

The Medresh Tehillim (78) quotes R' Yehuda in the name of Rebbe, “Three times that which is soft penetrated that which is hard”:

1) After the Philistines took the Holy Ark, the verse says, “He (Hashem) struck them.” How? When they would sit on a copper commode to relieve themselves, a rodent would come and the commode would crack allowing the rodent to tear at the intestine of the Philistine.

2) When B'nei Yisrael were ready to conquer Eretz Israel, Hashem sent the Tzirah (a type of insect) to fight the nations of the land. When the Emorites came out to fight B'nei Yisrael, the Tzirah went out and injected its poison into each of their eyes.

3) When the arrow of Na'aman went into the armor of Achav and killed him, the verse says, “A man [of Aram] drew his bow aimlessly, yet hit the king of Israel between the joints of his armor.”

When it comes to Divine Supervision sometimes Hashem desires to reveal his interaction on our behalf in an open manner. At other times, though, Hashem wants to insert Himself in a more subtle, yet miraculous, manner.
